Did another get to know the new rig trip for two days up-Island checking out work done so far.
Turns out the usual driving around plus solar- same driving around as when using the 5er and truck before (library, groceries, dog park, etc), restores about 25 or so AHs a day. Mostly from the alternator charging at 20+ amps.
Was stopped for a while in the bright sun ( was a low sun at 11 am on 22 Jan at 49N) and was getting 5.4 amps from a 255w panel lying flat on roof with MPPT on batts able to accept more than that.
So not much out of solar even mid-day this time of year at this latitude. Which is why I never bothered with solar for camping here before with the 5er until the sunnier half of the year.
With that 25AH info, and knowing our typical AH usage, it looks entirely possible I won't need a generator with this MH.
Boo-hoo--my days of charging the battery bank with 155 amps doing 50-90s with the Honda 3000 may be over! I have the 55 amper on the two AGMs and the 100 amper on the other house bank of four Floodeds, but recharging at home does not need high amps, since there is lots of time. Don't spend more than four or five days away in the dark half, and have enough batteries to get by with that 25 AH assist. Later, staying away longer it will be good solar conditions plus the driving around. Can reduce the other house bank to two Floodeds then too, based on experience with the 5er camping in the same place same time of year.
Scenario is everything.
(This whole Class C thing vs 5er is taking a while to get used to.)
