Any help would be appreciated and thanks. LCP
When I pulled a TT, and then a 5thW, I had a Generac 3600 permanently installed in my pickup. It pulled gas from the PU tank, and started from the PU battery. When needed, I plugged the trailer power cord into the socket that was added to the housing of the Genset. It was done working with Holley Generators in Sacramento. That is THE place to have genset work done if in NCal -- of an size.
The only problem I had was that the 3600 was not large enough when in higher altitudes - and I wanted to pass that info on to you. As a final test "before" we started the install, we set up the genset so I could run all the stuff I wanted to be running at the same time. Primarily that was computer, TV, A/C, and charger. It worked great. The first weekend after the install, I drove to Boomtown in Reno (EL 4700). At that altitude, I was not able do the air and charger at the same time. There is a formula that slips my mind, but it's something like so much less power per each 1000 ft. above 1000 -- or something like that.
Have attached a few pics that you may find interesting. Note that when hooked up, I also had a remote start cable installed. Inside the rig, the genset start switch was custom mounted on one of the wall panels. In the pic showing the hookups, I am parked beside the rig whereas other times I would not even unhook the PU such as an over night stay. Also note the housing that muffled the sound. It was made of the same kinda material trailers are made of that is very strong and very light weight. The inside was lined with sound deadening material. The sound test that Holley does is that you should be able to carry on a normal conversation standing just beside the unit.
Bottom line, unless you are a camper that can get by with minimal power -- go for as much power as possible considering needs and trailer size. For me, a minimum of 4000 is needed - and on my next rig, I will go a step or two higher. But then, I run my business from my rig full time.
