Just caught Mickey with the original Victor mouse trap. Unfortunately, Minnie has just shown her face. So hopefully we'll get them all. DW hates mice and will jump a mile if she sees one. We're on a camping trip and this is ruining it a bit.
We had the Rand McNally, functions were OK but unit quality was horrible. Locking up, screen brightness, short battery life, and after the 2nd unit (camping world replaced first unit) Rand phone service was terrible... We now have the Garmin RV760, great unit, quality, and American made with American service. As far as the RV features vs driving without the trailer, simply switch it to car mode and it will ignore the RV settings. I recommend the Garmin .
I recommend the Garmin too. However, it is made in Taiwan which doesn't quite qualify as American built :)
If your Jayco is like mine you have a separate 12v wire and fuse that feeds the landing gear from the battery. I had blown that fuse and experienced the same symptoms. That's the first place I'd check. Use a meter, don't trust looking at a fuse. Or replace it with a known good one and see if that solves the problem.
