Sorry, I just saw this thread with your questions. Yes, I bought them from Command Electronics. All the details are in this post:

(IIRC, TM's own cigarette lighter sockets are fused pretty low, at either 3 or 5 Amps each.)

Actually, the cigarette lighter socket in my TM is rated for 7 amps, which is 96 watts at 12VDC. So that would be plenty for the CPAP. The CPAP our guest used was also about 60 watts, and we used it for several nights powered in that socket with no ill effects (via an inverter, actually).

(The 1040T is about 20% "more" battery, in weight and capacity, at about 20% more cost.) them. It's about taking in the high charge current without overheating - not about "maintenance free".

Where have you read that Trojans (the T-105s and the like) aren't well tuned for being charged by solar setups? Most battery literature I have read, including the windsun.com site and Trojan's site, say deep-cycle batteries should be charged at no more than the C8 rate (or sometimes the higher C10 rate). At the C8 rate, a 2-cell T-105 bank can be charged at 26 amps. Is your solar array putting out more than that? Looks like the setup you just described above is only ~12A (153W).

Ah yes, can't help you there. And I too hate frozen beer. Had a whole case explode on me when I left some out in Utah in January overnight a few years ago. Bad scene. Maybe use a cooler?
