Lifepo4 battery in 1990 Lance?

The Prosine 100amp charger part is PF corrected ISTR, so the 2200 could run that going full out at 14.6 at 100 amps AFAIK. Itinerant does not charge at 14.6, but at 14.1 with his LFPs so that does help when using a smaller gen too.

Our Class C has no gen (it was an option the original owner did not choose it seems). A 2200 goes in the gen compt, but not the 3000 we had, so am using a 75 amp charger-max non-PF corrected the 1700 running VA rated 2200 can do.

So that's where I got the gen size limit. If we could have room for the 3000, we could run 150 amps like we did with the 5er we had--the gen went in the truck bed with the 5er.

Where do you carry the 2200? We have no room in the TC to carry any gen, and the truck is full of dog crates. The gen smells of gas anyway, so no good in the truck. As it is we don't need a gen for how long the TC is ever off-grid. Long off-grid time means use the Class C.

“Where do you carry the 2200?”

I have a 09 Eagle Cap 995 and it originally came with an Onan option in the drivers side rear wing...But I’m not so much a Onan fan, so when I ordered the build I had them delete the rear horizontal genny door in lieu of a street side, in-the-wing vertical door, just large enough to slip the 2200 thru and a few supplies... Our previous 05 Citation 9-6 had no such provision, so lesson in packaging learned...

In retrospect, I was uber lucky that Eagle Cap agreed to accommodate that on-the-fly change... The opposing wing has two 30# LPG bottles, so they used the same dimension door... I believe the standard build is mostly with the emphasis on options, of which the Onan is a dealer cash cow...Also, has 60gal fresh water and 2” walls... It’s primarily for these reasons and off-grid camping that I pulled the trigger... Spent a bunch of time reconfiguring the entire electrical to what’s now a passive-cascading (smart) whole camper system with two sub-panels and two ATS switches... Can run the AC for about 3 hrs (compressor cycling...) from the 200a/hr Li concurrent with solar...

Lots of calculations can be made. One thing to remember is that with a 5er you can carry lots of batteries and a big portable gen to run a big amp charger, so you can take advantage of Li charging amps.

(But then I would say since you can carry all those FLAs why spend all that $ on LFP? Seems silly to me.)

few reasons, that are simular to reasons in the TC. Weight being a big one, at 80 lbs each I would been 6 to get the same usable output, which I am thinking of doing... but at almost 90lbs for a rolls surett thats puts over 500lbs at the front of my 5th only 5 feet behind the pin. how much extra tounge weight do you think that adds compared to 80lbs that I could put say 10 feet behind the pin. huge difference in load on the truck. also at about 300 bucks per battery (I dont buy cheep lead acid batteries, I learnd my lesson from doing that), I am at 1800 bucks for lead acid, hmm I think I was at around 2000.00 to build two 280 ah li banks.. plus instead or 800 cycles I can get up to 7000. LiFePo4 are probably now the cheepest per usable AH in the market now, this want the case a couple years ago, then when you look at the longer life they become even cheeper over time.

also if I wanted a Generator I would have never put solar on, personaly I hate camping when there is some one with a generator around, I go out for peace and quiet and enjoying nature, not to listen to the power fist generator hammering away all morning because some one couldnt have spent a few extra bucks on the 80K trailer to put solare and decent batteries in...

Yes, I forgot you can have a weight issue with a 5er, especially if you have a Diesel truck with 4x4! We had no problem with the gas truck 2x2 and our 28.5 ft 5er for what we can carry in the box. The new trucks are even stronger than our 2003, which was a jump from before that. Good thing!

Anyway, the whole point is to do some serious calculations for your own scenario and not just get caught up in the fashion of the times. Nobody else is in a position to tell you what to do.

Not clear if we answered the OP's question for his situation. At least he has some factors to mull over that ought to help.

“also if I wanted a Generator I would have never put solar on, personaly I hate camping when there is some one with a generator around, I go out for peace and quiet and enjoying nature, not to listen to the power fist generator hammering away all morning because some one couldnt have spent a few extra bucks on the 80K trailer to put solare and decent batteries in...”

Ah, Soooo TRUE, I couldn’t agree more!!

Carrying a generator has never been a problem in any of the RV's I've had..I usually just set it in the door and unload it when there...With my TC,I carry it in the back seat..The old days were simple,just use the battery as needed then run the generator to charge it and anything else needed charged and watch dvds while doing so..I am almost always in the shade under trees because I camp exclusively in the national forest of Idaho boondocking where any generator noise is only heard by us...

I'm still on the fence of going lithium and either upgrading the converter or just using a good portable charger..The cold weather here could be an issue for it and the Sio2 is not off the table..If I put the new battery in its place,weight is not an issue,if I was too use it portable,then weight is an issue...$500+ batteries are hard to swallow for me..lol

Thanks for the replies..
