Thanks for the input, Dan.
I'm beginning to wonder if these things aren't more trouble than they're worth. We've only had one real sojourn in the Plus yet it's consumed more time and effort than I care to add up.
I put a level on various flat surfaces inside and outside the unit and there is definitely a 1"+ lean to the side that has the refrigerator--which I assume is causing the lean. I find this ironic because in the frig manual it says that the unit must be level in order for it to function properly.
I also talked to the parts person at the truck dealership who said I was correct to order the 80 PSI Cat's Eye (after I mentioned that Ford suggested a lower inflation pressure) and he said, "You always go with the tire manufacturer rather, than the maker of the vehicle." I still had my doubts because I got the impression he didn't want to reorder another Cat's Eye, so after hours searching and reading the Bridgestone/Firestone website, I found absolutely no information regarding my dilemma. Finally, I gave up and emailed my specific question to them, but they haven't replied yet. So now I have an expensive piece of equipment ready to be installed that may be a waste if it's the wrong type.
Ever get the felling that the world is overrun with Sorceror's Aprentices?
And finally, I'm finding that my house battery isn't being charged when the unit is plugged into 110 AC--so something must be draining the thing, but for the life of me I can't figure out what exactly!!!
Sorry for the rant, but when I share these problems with my wife, she just shrugs and asks if we made a mistake? AGHHHHH!!!
