Of all the RV's I've had, I've never had a TT. My FW would get batts charged via the truck when travelling. Isn't that the same with modern TT's? My point, if you are always going to be hooked up to power, why spend extra money for higher end batteries? Is this getting overly complicated? A simple 12v standard battery should work fine, shouldn't it? 2 in parallel should be plenty- even with a day without power provided good energy management.
the problem is the actual voltage by the time it gets from the alternator all the way back is lacking. I have seen them using the 7 way measuring as low as 10V with load on it, others have said lower but it makes me wonder about their meter haha I don't have power going to either my camper or my 5th wheel from the truck because of this, I use the solar to charge while I am driving. I am adding dc to dc to both for emergency use (its already in the camper, just a 20 amp renogy thing for 100 bucks CDN.)
he could do that if he added a cheep dc to dc it would make up for that low voltage by drawing more current so if he got say a 10 to 20 amp dc to dc that would work fine. he also has 200 watts of solar to help with the driving part. I think between the solar and a small dc to dc he would be covered. even if he is at 60% (60AH) a two hour drive with the DC to DC and the solar should be able to keep up with the fridge and make his battery full when he arrives any thing over that he could turn off the dc to dc and only use it as needed.
Agreed. That's what I was trying to say but you said it better.
