Xxxreme: thanks for that table. I have never seen that info.

That data says that the configuration I have tested might not run in theory. I can tell you it does for me in practice. Even with all other LP draws at full (stove, refrigerator and water heater) there is no measurable voltage drop.

When we travel I carry the two Honda 2000s on a platform with two 20 pound LP cylinders. Each can be run from a dedicated 20 pounder, or they can share a 20 or one or both can run off the LP port. All of those configurations use 1/4" plumbing with quick disconnects. Despite warnings, labels and tables, I have tried every combination that I carry under load (either the real load of the trailer with AC running or simulated load of a hair dryer on full on each generator) and with a voltage meter I see zero voltage drop.

Clearly the data you provided says some combination of engineers, lawyers and warning label printers advise against running that much generator off the LP port. I didn't know that and appreciate the info!

We will likely only ever need one generator, but we like this package because it includes a 30-amp style outlet with an adapter that bonds neutral to ground and lets us easily plug our 30 amp RV cable directly into the generator.
We've just purchased a 2017 FC 25 and will be full timing for the next year I know that we'll need AC at some point so we're considering the RV 4 package.

Question: The 6' hoses come with low pressure regulators. Are these necessary when running the generators off of the low pressure port?

Congratulations on the new Airstream, welcome!

When running our GenConnex EU2000i Companion off the low pressure port on our trailer, we use the 12' hose that has a 1/4" adapter on one end (for the port) and a 3/8" adapter on the other (for the generator). The shorter hose with the regulator is what we would use if we wanted to connect the genny directly to a propane tank.

At least one person with actual experience (GammaDog) has successfully operated a pair of EU2000i generators off the low pressure port with a "T" and extra hoses and it looks cool. That might work for you as well, though (fair warning) the fine print says it shouldn't, and GammaDog's latest post here says he's also using a pair of 20 pound propane tanks, one for each generator.

Wired acquired the splitter from GenConnex that goes on a 30 pound propane tank to run both 2000 watt Honda generators air the same time. They said a 40 pound tank might be needed in the cold at altitude.

It's great to know that in practical use a 3000 watt generator can be run off the LPG port. I guess my only concern is whether or not fuel starvation is taking place and causing an improper air/fuel mixture ratio leading to excess wear and tear on the motor.

For the meantime, I will be running a 3/8" line from my 3400 watt generator direct (via regulator) to a propane tank.

Note that the issue is how fast the liquid propane can vaporize to a gas state to run the appliances. Thus cold and altitude would not be helpful and the reason for GenConnex saying a minimum of a 30 pound tank to run two 2000 watt Honda generators. We have an assortment of propane tanks, so that is not an issue for us - 30, 20, 10 and 5 pound tanks

Hello all. I just wanted to share that I spoke with Gary at GenConneX today after reading this fantastic thread. We first spoke about "not starving" a twin 2000's set-up if using the onboard propane tanks through the trailer's 1/4" QD port. Since I'll have a 30' trailer, and I was thinking I'd like the QD connection at the back left corner of the trailer, he recommended that we use at least 3/8" tubing (but if I'd ever use the EU6500 discussed below, the 1/2" ID tubing) would be better to overcome the "friction" I'd encounter with that length of a run, then terminate with a 3/8" QD fitting. I told him that I wasn't 100% committed to using the onboard gas for this purpose, and that I might stay with separate LP tanks that are more easily refillable ... he sent me a price quote built with both solutions. Regardless, I just thought I'd offer the 1/2" line advice. From the price quote:

GXG LP-EU2000i-SA-EC, $1499
GenConneX Honda EU2000i Propane modified generator with quick-disconnect propane inlet, 6ft quick-disconnect propane hose and regulator.

GXG LP-EU2000i-COMP-SA-EC, $1599

GenConneX Honda EU2000i COMPANION Propane modified generator with quick-disconnect propane inlet, 6ft quick-disconnect propane hose and regulator.

GXA Gas Hose LP 12ft 3/8 Dout, Qty 1 @ $129.99 (use with on-board propane tanks)
Low pressure propane 12ft x 3/8in id extension hose with 3/8in male (in) quick disconnect and two 2ft x 3/8 id extension hoses with 3/8in female (out to generator) quick disconnects for dual generators.

Propane Splitter 2-ACME, Qty 1 @ $39.99
BBQ Tank output splitter to connect two regulators to a single 20-60Lb tank (requires ACME to POL adapter to connect to 100lb tank)

GXA Propane Reg w/6ft hose w/QD GXA, Qty 2 @ $49.99ea
GenConneX 6ft propane fuel regulator hose assembly with 3/8in female quick-disconnect

GXA Elec Par Cables EU2000i, $49.99
Honda Parallel Cables for connecting two GenConneX Honda EU2000iS generators together (NOT FOR HX MODELS)

GXA Elec Adpt L5-30P to L14-30R, $89.99
Power adapter 1.5-Feet Female Locking Adapter for 125-Volt L5-30P Plug to 125/250-Volt L14-30R (Two hots bridged)

Oil 5W-30 Syn Mobil Shipping UPS Ground, $0
Motor Oil, 5W-30 Fully Synthetic Quart & funnel

Shipping charge for UPS Ground delivery from Hingam, MA to Northern VA is $69.99.


On a separate topic, we also spoke about my other generator, an EU6500 that I keep for emergency use at the house. I told him I was inclined to go with "the other brand"
conversion kit, but he told me about the GenConneX conversion. Unlike the other brand, the GenConneX kit involves a full gas tank replacement where the conversion is self-contained within the existing footprint of the generator and with no bolt-on appendages to snag or break (the main reason I hadn't previously performed the other vendor's mod). He explained that it's very easy to install and it comes with both the propane and natural gas fittings to run the generator. Unfortunately, you can't run gasoline through it without reinstalling your unmodified gas tank, but I can live with that. It's not on the website and not in stock right now.

GXK LPNG-EU6500is-Kit-1, $699.99 plus $29.99 for shipping
GenConneX Honda EU6500is Propane &Natural Gas conversion kit with quick disconnect inlet and 12' low pressure natural gas hose with 1/2" male in quick disconnect and 3/8" female quick disconnect for conntecting to generator.

I should have asked if they have a natural gas adapter for the EU2000's as well... In a winter-time power outage, they'd be much more convenient to deploy and would be more than sufficient to run my TV, gas fireplaces and fans to circulate heat, along with a couple of lights...

Good people. I'll buy from GenConneX when I'm ready to pull the trigger. I'm very impressed. So glad Rocinante started this thread and introduced me (us) to GenConneX.

Regards,
Rich

Thanks for all the parts and pricing info!

I just spoke with the service writer at the local AS dealer. He told me I couldn't run a generator direct to "one" of the propane tanks because I would get air in the line. I didn't think I could get air in the line just by leaving one female propane attachment unfastened?

Anyways, he said I would need an in-line adapter in order to basically steal propane directly from the tank without interfering with the AS setup. Anyone know of which dual feed adapter plugs in-line before the regulator on the AS?

Having the 3 fuel option is a terrific plus, I think. While I don't mind carrying a gas can in the bed of my truck, I would rather not have it back there for obvious reasons. Using the quick connect on the front of the trailer makes this a lot more convenient -- and safer.

Boy am I glad I found this thread and this post. We have the Honda eu3000i handi and would love to get it converted to propane and run it off our front low pressure port.
Is it possible to get a little more into as to what's involved and how should I contact to get this moving.
Thanks
Doug

Doug, check www.genconnexdirect.com and www.motorsnorkel.com ... There are others too, but these are the two most popular, IMHO. genconnex does propane only and propane and/or natural gas ... US Carb (motorsnorkel) does all three (gasoline, propane and/or natural gas) but has an externally bolted on appendage. You need to visit the sites and query a lot to inform your decision. Rocinante's video earlier in this thread is awesome to show you the genconnex solution... Bottom line: only you can decide on your needs and compromises. Note I have neither yet. Good luck!

Regards,
Rich

GammaDog,
I'm waiting on a 2017 28' International Serenity with 2 a/c units. I purchased a Honda eu2000i and Eu2000i companion. I included the solar package in the deal. My wife of 35 years and I have enjoyed tent camping and pop-up tent camping with the kids and are ready to enjoy the Ritz version. We have worked hard to afford this chapter, just want to make sure we're investing in the right gear. I think the propane Honda eu2000i is the right decision.

I converted my EU7000is, with the GenConnex kit, full gas tank replacement, conversion took about an hour and was well written out. Has worked flawlessly since.

I concur. The Genconnex conversion is internal and efficient. I have nothing but high praise for Gary and his Genconnex company.

Not quite sure if he's correct if you have an automatic change over regulator. Technically the regulator is only pulling propane from one tank. You would disconnect the tank that is not use and use it for the generator. I've disconnected an empty tank hose to refill the tank while the other tank is in active use. I've never experienced a negative repercussion in doing this.
