Labtek; I have already driven 1500 miles in two weeks!. I will average about 500 a week for the next couple of months,then about 1200 a month. I do not expect mileage to increase much, but I am having so much fun with that engine that I really don't care (a different tone will prevail when gas returns to $2 a gallon!). I had driven about four different brands from a couple of Rialta's, and three van conversion brands, one with fancy air bags, that could be adjusted from the cab and all at least 20K more new, and none with the same room. They all were rather vague on the highway. My Trail Lite is much more stable (due to the duals probably). I plan to use the slide a lot, and that may be achilles' heel in the construction. I suspect that the mechanism was not designed for repeated use, and may begin to separate over time. Added screws will help there. I plan to put a swivel under the passenger's seat at some time in the future. I also plan to get some pads for the couch and dinette (for better sleeping). Both are only about 40" wide, and though the unit is rated to sleep 4, I suspect that they grow pretty small people at the factory!
Since I do not plan to sleep in the unit much, I am not much concerned with that. In fact, I have been thinking about getting a sizeable trailer in the future to pull behind the B+ when I am retired and want to stay in one place for longer periods than a couple of days. Sorry for the long reply.... I have obviously been obsessing a lot over this vehicle over the past few months!
