Glad you want to continue camping with your daughter. My sister and I camp with our daughters all the time and leave the menfolk home. We go out at least 12 - 13 trips a year and have so many wonderful memories.
I know there are a couple of folks that tow a long trailer with either the Durango and the Grand Cherokee. Personally, I would not want to. When we were looking to move up from our pop-up, I wanted to stay under 25 feet both due to the wheelbase of the SUV and longer trailers not always fitting into sites we like... I also wanted to stay under a trailer GVWR of 6000lbs with my Durango just because i have towed at max weight before and did not like it. So, if you want to keep your current trailer, I think you should be looking at full size SUV or truck. You already know that with a different trailer, you open up alot of possibilities for the TV that fits you and can do the job.
