Running roof ac while driving

What exactly did you mean by energize the truck or trailer with the generator? Im planning on having the gen on a hitch platform behind the trailer. Then run the wire, which is like 30amp right, under the traler and up into the junction box. There ill have a shutoff swtich for it so i dont risk having shore power ruin the generator. The generstor that id be usig has a 12hr run time. Id stop way before then both for fuel and to let the dogs out. They would have a worse time riding in a cage. They have never been in a cage in their lives and would probably lose it completly. I'd love to be able to buy a new one. If I could I'd just buy one like someone said earlier with a gender already in it and be done. Or even better buy an rv and be done. But unfortunately the check book gave me a mean look when I mentioned that idea. So I'm with buying a used one. I've rode in my uncles camper, he has 25 ft something or another don't remember the make. I'll admit it's not the most comfortable thing in the world but I wouldnt have a problem with riding there for a trip. I can't put my monsters in the cab of the truck each one takes up an entire bench seat and I'll have 3 passengers plus myself. If it was just me they'd ride in the cab no questions asked. Before anyone else asks no I can't have someone watch them. They scare most everyone and only obey me, which is how I trained them. I know it gets hotter than hell in the bed of the pickup. I put a thermometer in there in the summer with all the windows open and it got way above the outside temperature.i even road in there to see if the wind makes any difference and I had to get out not even 10min down the road. S s no way a polar bear (great pyrenees) and German Shephard could ride in there.
