With my 1st 5th wheel the dealer told me that I could tow it with my 1/2 ton Chevy Gasser. I towed it once and when we came home I told my wife we either sell the 5th wheel or get a bigger truck.
It did tow it BUT I had to be aware of hills and get sort of a run at them and the stopping factor was not good either. I was white knuckled the whole time and not a pleasant experience.
I upgraded to a 2500HD Gasser and it was like the trailer was not even back there.
I have since upgraded to a 2500HD Diesel and also my 5th wheel which is heavier. It has three slides where the old one had only one. Same length at 31 foot. The diesel handles it BUT when it comes time to upgrade I'll be looking at a 3500 or F350 for sure.
The daily driver is not an issue for me as I have always enjoyed driving a truck over a car although there are times such as WalMart I wish I had a shorter bed than the 8ft back there but I get by.
I wish you luck in finding the right solution for you!
