Since everyone mentioned what I was thinking, here's a different thought.
You've done this before so you know what you need to travel- can you function in something smaller than the 36' behemoth you mentioned? My 31' C can easily tow 5k because it's rated for double that, but if your lifestyle requires you to have more space, then it's an A. If you can't imagine yourself in 25-28 feet (didn't know B+ were that big!), Then a B is out.
If I was FT, I would pull a trailer fill of toys, or drive a toy hauler, not pull my bike out of my truck every time I wanted to use it.

May you find Peace in all you endeavor.
