I'm going to suggest something despite knowing many things such as: what type of hitch you want, what color your truck is, and how much your dog weighs... :D
We are on our 3rd Jayco, so I'm biased. However, we are shopping for a new rv as well, this one is 10 years old and we've gotten our monies worth out of it. We have 2 kids and a dog, and my truck can only tow about 9800lbs comfortable. I my rv pad at home for storage is only about 27 feet. The trailer we are considering is the Jayco Whitehawk 24MBH https://www.jayco.com/products/travel-trailers/2017-white-hawk/24mbh/
It has full sized bunks in the back, a queen size Murphy bed in the front, with a couch when the Murphy is folded up into the wall. The dining area has a slide full sized slide. The bathroom has its own door on the left side of the trailer (great for cross venetalation).
The only thing I don't like is the outdoor kitchen, if we buy it I'll probably gut it and use it for storage.
Anyways, thought I'd through that out there in case you needed more confusion. Take your time buying your rv, see what's out there.
