1 year later in my 2021 AI GT (mods and lessons learned)
So, after having my Interstate for a year, I thought I’d post a list of all the modifications I did to either 1) correct factory shortcomings such as the weak drawer latches and incorrect lithium settings and hardware, and 2) make the RV more functional and enjoyable.
My list is in order as I did them. I’ve asterisked the items I think are necessary or highly recommended for any new AI owners. Details for many of these items can be found in other posts from me, or others that I borrowed the ideas from (the "Interstate Mods" thread is a great place to start for new owners).
- * Replaced 3lb. drawer latches with 10 lb. (10#) to stop the drawers sliding open during turns (On the drive home from the dealer, even with the drawers empty they were sliding out. Very disappointed)
- Systematically attacked the squeaks and soundproofed the rig as much as possible
- Re-programmed inverter for Lithium charge settings (this is well documented in this forum but the early AIs with the Lithium packaged did not come with the right Magnum lithium compatible charger)
- Installed hood bug deflector and window wind deflectors
- Replaced OEM horns with Hella super tone horns b133 (to get rid of the “meep meep”)
- * Installed cab curtains (Those magnetic front cab window shields were a pain. I much prefer the cab curtains, especially if I’m pulling over to a rest areas for a quick nap. it’s 30 seconds instead of 6 minutes)
- Tinted front windows
- Purchased and added teak floor for shower
- * Installed internal LPG switch
- Hardwired radar detector and dashcam
- Installed WeBoost Drive RV (cell phone signal booster)
- Mounted and hardwired 2 Streamlight rechargeable flashlights (one in front, one in back)
- Added Echo bluetooth brake controller for towing my trailer
- * Installed DT Pedal Box (I recommend this if you are not satisfied with the acceleration delay in stop and go traffic)
- Added RennTech ECU tune
- * Added Victron SmartConnect Shunt 500Ah (A necessity for proper battery management)
- Upgraded OEM inverter to Magnum MSH3012RV-L Hybrid (3000 watt) so I can run the A/C or Microwave for a short period off the batteries. And also because the factory inverter was not lithium compatible.
- Added 2 more BattleBorn batteries (400 Ah total)
- * Added EasyStart for A/C
- Added FireFly Vegatouch Mira Bluetooth module (extends the panel touchscreen controls to my phone)
- Added Dually valve stems for easier access to adjusting air, and for adding TPMS (See below)
- * Added TST 507 Tire Pressure Monitoring System (if yours did not come with TPMS, you should add it)
- Replaced rear LG TV 24" with Smart LG TV 24” (so I scan stream movies, etc.)
- Added Bose Bluetooth Soundbar to rear (I installed this under the LG TV. Also nice for playing music through the back screen doors, or easy to remove and plug into the external 110V outlet while sitting outdoors.)
- Replaced OEM lug nuts and chrome covers with Alcoa dually lug nuts from Amazon. If you rotate your own tires like I do, getting rid of those covers definitely saves time and frustration.
Next on the list: - Alarm, maybe with remote start
- Fresh water tank quick drain
With the above done, hopefully I can get back to restoring my project cars!

good update: similar, but some of mine:
Added Amazon Firestick to allow streaming on both TVs (Lounge)
Installed iPad for navigation, I use Waze exclusively.
Replace factory tires with Michelin Agilis (massively quieter)
Bought 4" California Queen mattress.
I would like to see your curtain installation for the front.

Oohh my wife is going to be mad I read this post! I have 3 questions:
1. How hard is it to install the smart shunt? I hate trying to monitor SoC of lithium batteries with stupid voltmeter on touch panel. I’m not terribly handy, but if it’s just opening a panel and plugging something in, I’m up for that.
2. Where did you put the two additional battleborns? Did you install yourself?
3. What has been your experience with the Vega module to control system from your phone. Read report from someone else who installed that saying it was very buggy and seldom worked.
Thanks!

Also, where/how did you purchase the Vegatouch Mira module? I looked on their website and searched the web and couldn’t find any way to purchase online. Did you order over the phone? Thanks.

Here's a link to my inverter / battery / smartshunt install. Definitely not a plug and play task but if a SmartShunt is all you're after, a dealership could easily add one.
On the Vega Module, I've been extremely pleased with it and had no issues. Here's a link to that install. This is something you could do yourself (plug and play), but no, you cannot order online, you have to give them a call.

Here are the cab curtains I bought from OMAC USA. You'll note on their website they weren't designed for the "Tall" Sprinters like we have, but I was able to bend the channels to fit the contour of our roof. The curtains themselves are not full blackout, but I find them sufficient enough and they are easy to tuck away behind the drivers seat.

"Replaced OEM lug nuts and chrome covers with Alcoa dually lug nuts from Amazon. If you rotate your own tires like I do, getting rid of those covers definitely saves time and frustration."
Would you provide more info. Possibly a link. I have looked for these for over a year.

Would love the same. I despise those foolish lug nut covers.

Two options I found:
1) Here's a link on Amazon to the lug nuts I purchased.
Note that there are a few reviews commenting on the quality of the chrome and that they may show signs of rust and pitting over time.
2) A more expensive / possibly higher quality alternative appears to be Gorilla lug nuts, #22148N, but I couldn’t find them in stock anywhere. I had previously placed an order for some from SFX performance but canceled after 3 months of waiting and ended up going with #1 above.
Some pics of them on my wheels:

It does appear that the diameter of the washer of the chrome lug nuts listed on Amazon is less than that of the stock lug nuts. I assume that too small of diameter is bad, but am not sure how small is too small. But to be safe I'd go with a washer diameter that matches that of the stock lug nuts.
I was surprised about one negative comment that the washers don't spin freely. It has been a while since I removed my lug nuts, and I can't remember if the stock washer spins freely or not. If it does spin initially it seems hard to think that it would still spin as you reach the required torque.

I've no idea what you're basing that on but the Amazon lug nut washers are actually bigger. And yes, they both spin freely until they are tightened.

That same review complained bitterly about these lug nuts quickly rusting. Hoping that's not the case, and look forward to some follow up in a month or two.

This is an older post, has several suggestions on location. Discusses several pro and cons on where and how to connect wires.

Weekend Bob how are those Amazon lug nuts holding up?
I have the same Alcoas and the dually valve stems that you have and if you have ever removed and re-installed one of the outside rears you will know what a pain it is to re-install as it is not possible to install the rubber stabilizer afterwards, it must be installed into the wheel first and guided onto the long valve stem from behind as you place the wheel onto the lugs. This is difficult in the garage let alone alongside the road and you can easily bend the valve stem out of place and cause it to leak, ask me how I know.
I came up with a solution for this problem, a 5" PVC coupling cut in half and wedged onto the axle hub with wood shims at the top so that the top part of the PVC is the highest point bringing it even with the outer top diameter of the part of the axle hub that centers the wheel. This allows you to easily guide the long valve stem into the stabilizer as you slide the wheel onto the studs as you are not trying to lift and support the wheel and tire at the same time. A 5" PVC coupling just happens to be the perfect diameter (both inside and outside) and thickness for this to work. I keep it in my side compartment just in case.

How about firefly working well?
Lastly did inverter cause you to want to rewrite ac circuits since now you have power to make full use of outlets with out shore power ?

This is the one question that always has me scratching my head on both the motorhome and travel trailer sides. If you’re spending the money on a 2-3k watt inverter, why not tie it into your electrical system so that you can run everything or a lot more appliances? This is like being half pregnant. Take advantage of all the power that your inverter has to offer and even better if you have a hybrid inverter that can produce additional wattage with the proper wiring. If you’re going to install these, you might as well go with the proper gauge wire to take advantage of the benefits of a bigger inverter and their boost functions or have the wiring in place to for future upgrades. Ok - rant off. WeekendBob great upgrades but I wouldn’t install an alarm in an RV. Can you imagine that going off in a campground at 3am?
Edit to add:
Adding a good video on how power assist works with some hybrid inverters:

Yes, Firefly is working well. If you are asking specifically about the Vegatouch Mira module add-on for mobile blue tooth connectivity to the Firefly that is also working well.
And yes, I did rewire all the AC circuits, doubled the lithium battery capacity, and upgraded the 12V wiring to make full use of the 3000w inverter to power AC, Microwave, coffee maker, etc. I documented that upgrade here: https://www.airforums.com/forums/f24...ml#post2493415
@Stogieman, I went with the Dronemobile alarm. Haven't had any issues with a false alarm but the other added benefits of the Drone Mobile setup is a) remote start b) gps tracking (if you subscribe to their service, which I haven't yet) and c) fast idle capability which is IMO, the biggest benefit to allow use of the engine for longer periods while boondocking to top off the house batterie instead of the much louder generator.
