Last year I bought a trailer chassis that had been for one of the gen/ECU setups. Didn't have the gen or ECU. It did have a couple small storage boxes and the fuel tank, but I removed those and painted what was left, as well as some clean up of rusting parts and whatnot. I had some wood 2x8s and used it as a utility trailer for a while.
So this last week I finally got my act together and make it a simplified version. Reinstalled the fuel tank and storage boxes.
First I mounted a nordic air 3 ton ECU
Then mounted a steel frame (2x6" steel channel welded into a rectangle 56" x 32") to support the gen. Used as many existing holes as I could in the trailer frame, only added a couple 3/8" holes on either side (of which there are multiple on the front and back for the other stuff that had been mounted before)
Other reason for the gen frame to be 6" high is so I can open the lower doors on the front of the gen to get to the wiring lugs, otherwise I'd have to unbolt the fender to access them.
Then mounted an MEP-802A.
Everything bolted down with grade 8 hardware.
Added a plywood bed for behind the gen, I have a tent I am going to try getting up onto it and strapped down in order to give it a little tail weight, as the tongue is pretty heavy right now (probably around 400-500 lbs) That and the BEOD are making it squat a little, but it sure helps soften up the ride (M1123)
The fuel suction port on the fuel tank was cut off flush with the tank, I plan to swing by the hydraulics shop next week on my way out to an event and see if we can't make up some type of fuel line for it, the tank is 55 gallons so I'd easily have 100 hours of run time with it filled up.
Next thing I need to do is replace the trailer tongue jack with something better, using a farm jack to hook/unhook the trailer is getting old really fast.
Oh, and the gen and ECU being the same height was just coincidence.
