Installation of the front SumoSprings was straight forward... no need to take the wheel off... no need to get under the AI at all...
  • Take all safety precautions. Place chocks in rear wheels.
  • Turn the steering wheel all the way to the right
  • Use a 13mm long socket to undo stock stop. If you are lucky the nut will stay with the socket, if it falls just stick your finger and slide it to the hole and it drops to the floor.
  • Lift AI via front lift support (in the Mercedes Owners Manual you will find the location of the lift points). Lift just enough for inserting the SumoSprings. In my case the wheel/tire was not even up in the air...
  • Insert SumoSpring.
  • I placed some teflon tape around the nut so that is was held in the socket. You can also use one of those magnets that you can insert in the socket to keep the nut in there as well... I was too lazy to use two sockets (short socket works best with these magnets to start the nut on the bolt)...
  • Tighten nut. I was able to do so until the whole thing started turning
  • Slowly lower back in place until the SumoSpring touches the A-arm and keeps it from turning. Finish tightening the nut.
  • Lower the AI
  • Turn steering wheel all the way to the left
  • Rinse and repeat for the other side.

Dash camera installed. I will see if I can get power directly from the rear view camera, if not I will route cable provided around windshield and connect elsewhere. For now the stock wire is just straight down and connected to the 12 volt outlet.

Mounted base to the plastic cover from the rear view mirror base. This way there is nothing on the windshield and the 3M film can be installed without issues.

Short video just testing (shared at 360 resolution just for test... but recordings are done at 720 and 1080:

Intermediate Door Stop Kit for side sliding door in place. This is to be able to open the door midway without closing on its own... this is a very small stop. Funny that they add a note letting you know that they did not forget to send it, lol... it is wrap around an ice cream stick, it is that small...

You fix it in place with some JB Weld.

Nice cam. Elegant design. We put one in ours, that interfaces video feed with the iPhone. Funniest vid to date was taken when our local Sprinter servicer did a test drive after servicing the transmission. I could tell that he was extra-enthused about the task, getting to drive a one-of-a-kind Sprinter like ours instead of yet another FEDEX van. LOL.

Consider running a water detection wire in your front pillar if it proves such that you have to go to the trouble of opening it up anyway. You should not have to worry about water leaks in that area for many years, BUT, it's not much extra money or time to run a wire in case it's ever needed in the future (blog post).

Also, if you think you might be doing other future upgrades such as cellular, TV, etc., you might want to lay extra wire in any area you open up. It's a pain to have to pull the cab apart repeatedly (voice of experience here).

Thank you again for the suggestions.

Okay. This seems to be the current version of what you have: Honeywell RWD42/a Defense Water Leak Alarm with Sensing Cable - the one you have can still be found but at almost double the price.

If I go in there, I will get the alarm and install it while in there...

Do the make a ride improvement?

Thanks

I have air ride so no need for them in the back. But here is the information on them:

Front 500 lbs (SSF-106-40)
Rear 2000 lbs (SSR-338-47)

You can buy them from several places. The links above are from Amazon.

And if you want more information on them:

https://www.supersprings.com/application-guide/

I have not taken it out after the install... but good feedback from those in the forum that have done the install...

Thank you wachuko,

I see on Sumos site they also have an airbag system that seems reasonable at $425? Wandering how this would perform.

I have done rear Koni shocks and upgraded sway bar already so just seeing what’s next best upgrade.

If you search the forum for SumoSprings you will find feedback...

I installed Sumo SSR-38-47 on the rear. This was the easiest change to make (vs Koni and sway bar) and some posts said it had the most impact. There was minimal increase in ride height in mine - certainly less than the referenced 1". But maybe my springs were new enough that they had not sagged. Or maybe mine was lightly loaded when installed - I don't recall. There was some improvement in the ride when going over dips and less rocking motion when closely following a big rig. They were a pain to install - but overall I would probably do it again.

I will probably never know the difference since I did not drive enough for a baseline... but this is one of the modifications made based on experience from others. Just like the Victron Solar control and the Blue Sea ACR... just for peace of mind.

The other one is this... now with the epoxy cured... tested. Works like a charm and no more having to open the door all the way.

Definitely better on my T1N - Mostly for larger bumps. (I have air bags on the rear)

Nothing new to see... only consolidating pending tasks/items list. Almost done with this list:

Not buying the rear door mounted ladder... so that is off the list.
  1. Hitch step. Went with the iStep 14" Black Aluminium Trailer Hitch Step and a no wobble clamp - Ordered
  2. 3M Clear (or Xpel) protection film for the front to protect headlights - Ordered Xpel for the headlights...
  3. 3M Crystalline film on windshield (clear) and side windows (legal tint) - to reduce heat inside while driving. - Appointment made for Jan 27
  4. Some sort of security mechanism for the EMS...might be as simple as a padlock with a short steel wire. I have a padlock, will just get the wire tomorrow at the local Lowes
  5. Ultra Breeze Vent Cover from Fan-Tastic Vent U1500SM - Smoke (I have the smoke color on my wish list in Amazon... still undecided if to go with it or with the one in white...)
  6. Bug screen for the above cover. U1550BL Ultra Breeze Bug Screen
  7. Install switch for LPG.. after all the work with the electrical... I want to wait before I start again on this one... just taking a break, lol.
  8. Add LED light at the back so it illuminates rear area when doors are open. Side LEDs are useless when the storage area is full...so must add another source of light. Thinking of going with this one
  9. Also...why no light on the side where you have to connect everything?? Had to use a flashlight during the hookup because it was already dark out... Airstream should install one on the driver side... I will look at this as well to see if it is easy to install one... I can always use one of those battery LED lights with magnets in the back and just place it temporarily on the AI while I hook up or when checking things at night... or just stick to my trusty LED lamp that I used last time.
  10. Paper towel holder - thinking of where to place it and how to hold it in place. I have seen some magnets with 3M tape behind them. Might get a metal towel paper holder like this one and place the magnets on the aluminum backsplash. Or see if this can be bolted under the cabinet... need to look more into this
  11. Leveling system (yeah... still want one... all I can say is that I am one lazy sob )
  12. Build second board (that can fold away for storage) for additional sleeping space for my son (daughter already claimed the one made). Low priority for now.
  13. Sound deadening material to wrap generator and bring down the noise it makes - have not used the generator, but best to do this now while everything is nice and clean... strange that I can't seem to find this locally... will have to order them online
  14. Looking at this thread for maybe doing something similar for the side glass/windows. Anything that will help lower the inside temperature of our Interstate in this hot Florida climate. It will also offer better privacy.
  15. If after installing the 3M window film we have issues with sun brightness, we will make side shades. Mara will help me with making these. Thank you InterBlog !

Deciding if I install the counter top extension towards the inside or matching the outside border... need to decide as I will be doing the install tomorrow. Thinking that it will be less in the way, and still functional, if I move it a few inches from the outside border... like in the photos.

Drawer removed just to make sure there is nothing inside that could be damaged by screws. I will use an additional board outside to reinforce the mount base for the hinges... will also cover the exposed wood panel with some fabric.
