I can't help a lot on the generator situation other than just keep searching the web. How ever, you can wire up the generator where you have a plug that is directly wired to the generator in to the area where your shore power chord is on the camper and when wanting to power the camper off of that just plug into your plug that is wired to the generator. That is very similar to the way my parents MH is.
I would really try to not haul the dogs around in the camper when traveling. I'm pretty sure that it's highly recommended that you don't travel with people or pets inside the camper. I don't want to start a debate, but if you can keep your pets in your tow vehicle I would do so. One example is; say your traveling, and the generator dies for what ever reason, now your pets are without cool air until the next time you stop... could be dangerous, and there are lots more reasons not to.
