We have had a ton of rain over the last two weeks, and I took the opportunity to open the slide for a good water test. It has remained dry as a bone, so hats off to the leak fixer at the dealer! We have ordered day/night shades to replace the rattly miniblinds, and are going to replace the existing side wall table mount with a freestanding pedestal mount. Still looking at options for reading lights in the slide; am concerned about voiding any warranty if I cut in to anything. All in all this is a great unit, even more so at the price. The new Chevy 6.0 V8 has PLEANTY of power and gives ~12 mpg.

Any tips on winter care and driving with this rig? We don't plan to mothball it as we like to go XC skiing in various mountain areas.
