We had been looking at class A's and when the wife could one she liked she wrote out a check, traded in the TT and told me to get something that was easy to tow. It took me about 6 hrs the next day to find something cheap (I'm cheaper then she is). I got a '13 Hyundai Elantra, put it in neutral put the key on acc and go. No fuses to pull, no speed restrictions and no running the engine in the morning.
We had 3 vehicles and none could be towed 4 down. I looked at a dolly and found it would be easier to keep the TT and hook up the WD bars. If you want to pull something just make sure it is easy and has the room you need.
