I just bought my first living quarters trailer and it doesn't have a generator. The issue I'm having is where to put it/haul it around. .y back is already bad, so I can't haul it in and out of the trailer. I was doing some research and saw that people have bought and installed slide out generator trays. I was thinking this might be a good idea to do in the back tack compartment, and then pull it out and just leave the back tack open while it's running. Does anyone have any suggestions? 

Unless you are going to take all your tack out, I wouldn't do this in case of theft, especially overnight. 

I would put it in the back of your pickup and make something slide out to the end of the tailgate so the fumes escape. 

Otherwise you can find someone to mount it on top of your haypod area, wire it to a push button from the ground.
