Thanks Klassic, you've got a lot of helpful info. In the end we bit the bullet and are having the dealer install the solar panels. They claim the 160 watt panels will serve our needs and at this point I'm going to assume that they are familiar with the wiring needs. It's going to cost us more, but with the trailer still being under warranty, I wanted them to do the work so they will have less of an opportunity to weasel out of any warranty repairs which might occur in the future. Regarding the expense, well I guess my kids can inherit it when I croak.
The dealer did recommend going 6v when the time comes to replace the batteries. I'm noticing a big variation in price. I assume this has to due with amp hours. More research needed I suppose.
