Genconnex Connection

Hi! I have a 2016 28' international w/ 2 ACs. I just orders the geoconnex package #6 with two 2000 watt hondas. My question is do I need to make any modifications to my aux gas port on my AS? It looks like on the genconnex website that it uses a 3/8" QD but it appears my aux gas port on my AS is 1/2". I'm not very knowledgeable in gas connections so figured I'd ask y'all.

Also, would I need to do anything special to hook it up to a regular BBQ propane tank?

I also don't have any experience with this, but I spoke with Gary at GenConnex just yesterday or the day before with the same question.

Clarification: I believe you're referring to the quick-connect on your A-Frame. This is actually a 1/4" line. It's deceiving - it looks like it's 1/2", but it's not. The ID is only 1/4", and the connection is a 1/4" low pressure connection (it is plumbed after the tank switching selector).

Bottom line: to run a pair of 2000's, yes, you will need to re-plumb a 3/8" hard line with a 3/8" connection. He has a 12' 3/8" hose, with a splitter and a pair of 2' pigtails for each of the generators. I've already found a propane gas fitter who will do the work for me in a couple of weeks... Good luck!

They (Genconnex) made a hose for me that has a quick disconnect for the port on the trailer that T's out to two quick disconnects for the two Hondas. I've run the AC with it. Ask if they can do the same for you. Good luck!

I think I have heard (several) reports of people running two generators off the standard LP port from the Airstream.

My bigger question would be why buy two generators? Unless you have a large trailer and must run both ACs at the same time, you could use just one generator and an EasyStart device.

SteveSueMac - I'm not an expert but my understanding is that, while you can, and GenConnex will, make a 1/4" quick connect fitting that will split to the two generators, they will run deprived (or "starved") of the fuel needed to produce full power.

GenConnex has a FAQ that addresses this. Per discussion with Gary at GenConnex, yes, you can, but you shouldn't ... It's best to replace the line with a 3/8" line to do it properly and allow the gens to run at full-power.

Thiel - I've been wondering the same. I bought two Honda 2K's this past fall - I only used them enough to break them in and change the oil 3 times. I filled them up in October with fresh fuel and Sea Foam and now, one works while the other is gunked-up. Dammit. I'm upset with myself and I'm definitely switching to GenConnex ... my only question is one or both (given your observation with the EasyStart). I have a large trailer with 2 A/C's ... wondering if I should just do 2 EasyStarts and have freedom to switch between one and two gens as needed. I understand that adding an EasyStart may void the warranty. Makes sense. Thanks, Rich

Thanks - I'll call them and ask about that. I appreciate the insight.

I have a 25, so just one AC which made the decision really easy for me. If you're going to camp in hot enough places to need both ACs, then that's a different calculation and I bet others have done it. (I think Matteo even ran a big trailer with both ACs like that off a single 30 amp plug, for example.)

I mention EasyStart just because I'm surprised how many people haven't heard of it yet. I'd researched it long before it came up on the forums here and it seemed like a no-brainer, but that's just me.

I don't know a thing about small engine repairs or electronics. I installed the EasyStart myself in just a few minutes. As for the generator, I converted it to propane when brand new because I feared the maintenance required of a gas engine (and I didn't want to carry the gas can, to refill it in the middle of the night, etc.)

I did not know about Genconnex admonition against using the 1/4 port, so I've got to look that up. If I decide to put on a wider port, I'll likely wait to do that at the dealer when I've got the thing in for service.

If you are going through the effort of getting an EasyStart on one AC, I'd go ahead and spring for both. We have two ACs (15 and 13.5) with an EasyStart on each. We can run either AC with one Honda 2000, both simultaneously with two Hondas, and both simultaneously from a single 30 amp source. The flexibility to run both ACs at 30 amp campgrounds is a big deal for us - one that I did not fully appreciate when we went down the Easy Start path.

Thanks again for this information. I emailed Genconnex today and the basic jist is that I probably should replumb the port on the trailer to the 3/8" size.

Longer story - the hose they made me is a total of 12' and about half of that is after the T so that helps the issue a bit. But running the AC with the microwave or while charging deeply discharged batteries would likely be a problem.

I happen to shut the AC off when using the microwave even on shore power but the batteries are charging all the time - now in 3 stages thanks to the upgrade there. But at some point, the generators will be "choked" and shut down if I have too much running unless I replace that pipe - so at some point, I'll talk to either an RV or Propane dealer and have that done....which isn't fun since I had that done at the AS factory and had I known, I'd have had them do it then....

Oh well - glad to know now. I have a few years to get this sorted as I'm still working right now and 99% of our camping is connected to hookups. I'll want the improved flexibility when really hitting the road in retirement.

Thanks again for the helpful insight! This will be a costly correction so hopefully others can learn on my Hard Knocks tuition

So I changed the 1/4" quick connect to a 3/8" quick connect. This is at the A frame. The trailer at that point is set up for 1/2" NPT plumbing. This is an easy thing to do. Gas NPT plumbing uses yellow tape. You can reduce the 1/2" NPT to 3/8". Check out the picture.

So I haven't even looked at mine. Are you saying it's a 1/2" pipe to the 1/4" disconnect and all you did was swap out the 1/4 for a 3/8? That seems simpler than I was expecting!

Well thats what is on my 2016 International.

My stock trailer had a 1/2" NPT male to 1/4" NPT male that went to the 1/4" quick connect.

So when you get your 3/8" quick connect you need a 1/2" NPT male to 3/8" NPT male adaptor.

Use yellow tape and be sure to turn off the propane tanks!

This is a low pressure port on my trailer.
