UPDATE:
Just got my Trail Lite back from a list of things needing correcting. My first concern was that the bottom of the slide was making contact when extended, and I feared leaking during a rainstorm. The factory rep told the dealer that this is planned, and the large seal at the top will keep water out. There is still some reinforcing that needs to be done on the front of the slide - just quality control. The dealer has several in stock and I will begin looking at some of the construction to see if they continued making some of the same mistakes. I had a fantastic vent installed (with the thermostat, but not the rain shutoff feature), and love it. When I ordered the unit, I didn't order the $300 CD player, so I installed a Kenwood, with a pair of Kenwood speakers in front. The stereo went in easily, but the speakers were a pain in the a**. the door has a rivited extension to accomodate the factory 6.5 " speaker, and I had to work with my dremel to fabricate a suitable secure mount for the replacement speakers (which frankly don't make a lot of difference in the sound). I believe I am going to put in a "canceling" phone jack in the back to mount some old Radio Shack bookshelf speakers I have to replace the factory speakers when I want to plug in the other speakers. I will have to use the other type of jack to not mess up the impedence of the rear speaker circuit.
I am still getting about 10mpg. Planning a trip to the Valley in Texas in about a month. I will drive 65 for that trip to see what kind of mileage to expect under the most conservative conditons.
still love it!
