I use to have a 28' All American Sport Toy hauler and I hated every second of it. It makes every trip with the camper 2x more expensive. You always take more food than you need. Your MPG will be but in half. You spend more time in the camper than riding. I had to store mine about 20 minutes away (PITA). Cleaning it up afterwords always takes about 2hrs. Your buddys will use it and trash it and not help clean it. Driving with the camper was a TOTAL PAIN and is hard on the truck, even with my dodge diesel. Ours would only hold 2 quads. PITA to winterize, mine always swayed at highway speeds, the list goes on.
The only pro's that I saw was acutal sleeping. Even then it was kind of a con at time. One of the first times we took the camper out he had kinda a late night so we all crashed hard and didn't wake up till 11 O'freeking clock!
Granted it was a quite camp ground, but still
I would really like a 16' enclosed trailer and make some flip down cots.
Here's a pic of my old setup.
