OP here again,
So I checked some pricing for solar and generators. Not sure I'm wanting to spend the money right now for solar when it's not always going to be useful, as in we like camping in treed areas. But I will keep watch on how much sun the roof does get during the days and gauge my further decision on that, solar will happen eventually I'm thinking, just maybe not right now but I'll keep checking for other pricing on the panels also. The generator I'd rather stay away from but perhaps in 10 yrs when Kim and I are on our own and just travelling about I'll consider it, just don't like the idea of bringing noise with me.
For now I'm going to get a third 6V, do some small trips of 4-10 days and see how we make out. We already do a pretty good job of preserving water and power so I'm thinking the third battery will be a good addition.
Thanks for the lists of items to take with us, most of them I've already got but I also took some great ideas out of the comments and lists.
I think I'm on the right track ...
Cheers! Happy Camping!! THANKS, Terry
