Solo with a TT is not hard. I did that for years, just me & the dog. As you get older the hitching and leveling also get old. What ever you buy, make sure it has a comfortable bathroom and maybe a walk around bed.
Eventually I also got tired of having to get out of the truck to go to use the bathroom while on the road. Now I feel much safer in a rest area. When I do go out my big black dog is with me. By the way, a dog that does not bark when left along is very important. I turn on the radio for mine.
