Almot,
Apparently #1 you have some way around drycamping for a week or more in conditions like BFL13 shows in his "Good luck with any solar here" photo on page 4 of 6 in this thread. I hope it's not the usual "I have battery capacity XX big enough to get by ... or my panels put out XX amps per hour even under grey skies ..." kind of arguments.
Apparently #2 you've never not-heard my Honda EX650 battery charging genny. You just might find yourself amazed. These can still be found for 1% of the cost of even a used TT ... or in my case for free.
First off, you're not supposed to "walk" on RV roofs ... you'd better be on hands and knees up there to distribute your weight. I'd like to see you move around solar panels to get at stuff on my waxed slippery fiberglass nicely crowned dangerous-to-be-near-the-edges RV roof.
Sleeping bag in an $$$ RV ... ridiculous, IMHO. I keep sleeping bags packed away where they belong with my other backpacking gear ... waiting for the next High Sierras trip.
So you canoe in the evenings when out and about camping in your RV? I don't ... I read books, watch movies, play board games, sort rocks/minerals/fossils, etc. in complete 72 degree comfort and top up the AGM batteries accordingly about every 3rd day with the little genny you'd better not be able to hear because you had better be camped farther away than that.
This is all in fun of course! (... until there's too many cloudy days in a row like we see all the time when we're visiting relatives in Washington ... then the fun stops)
