The only person that can make this decision is you, but here are a few things to think about.
1. Are you going to go toward a warm climate (south)? or are you going somewhere that can get cold? If cold, you are going to need something that has some pretty decent insulation and that is hard to get with a TT.
2. Do you like to entertain? If even 1 person, get an RV with a slide. It makes a world of difference, especially if you are living in there fulltime.
3. Have you ever driven, backed or pulled any kind of trailer? It can be intimidating, but is not hard to do.
4. I have no idea what your $25K will purchase in the Class A department, but I know that in this area, the $20K will purchase a pretty decent TT. Our friends have a Tundra and the mileage it gets towing is pretty awful - 7.8 mpg!!! That's pulling an HTT. We get at least 10 mpg with our Ford PU and that's pulling a fifth wheel that is 3 times the weight of theirs.
Just my $.02 worth.
