your best Mod so far?

I don't know. The only I've seen were axle mounted,
But
They were on arms that fit above and roll down.
You're right my lift might make room for it all to work.
I think my black tank is in the way, but I'll cure that.

We'll know before the year is over.
I can put chains on pretty quick but there is really no worse job than installing chains.

The pic is four sets, 8 wheels of v bar chains and tighteners awaiting a mount to put them in the polaris's ranger and sportsman.

I'm all about chains and winches and 4x4.

I'm not sure how they get put on. I know a guy who is a county snowplow driver in upper Michigan. That is my closest personal experience. If you could put chains on in your shop at home and then drive to the snow that would be easy!!

Furnace blower minimal

Just ordered two MaxxAir Deluxe fans. They're supposed to be ultra low amp draw. Will test after install for proof.

Based on this, I would require something like 12kWh to run the A/C overnight.

Your air conditioning data seems unusually high, even if you have the optional 15,000 BTU/hr unit; which I assume you do. In any case, if running it overnight when there is no sun and temperatures are much more favorable, A/C power requirement will be much lower when compressor is operating, and duty cycle will be much lower as well. You may need 12 kWh for say an 8-hour night, but I doubt it would be that much.

Just finished helping with design and installation of a similar upgrade, but with greater lithium capacity and two smaller air conditioners. Motorhome is roughly same size as your 24F. While taking initial data, it is obvious that each A/C power requirement will vary significantly depending on temperatures. In evening with inside and outside temps in the low 80s they only pull around 8 Amps each, or just under 1,000 Watts. However, if turning A/Cs on when inside and outside temps are both 90 F or higher can easily lead to current in 12 A range, or 50% higher.

Just mentioning this to make everyone aware that running A/C overnight from batteries isn’t that impossible or cost prohibitive any more. This is particularly the case when the motorhome has a segregated bedroom area with its own small and efficient air conditioner. Unfortunately, your 24F’s open floor plan requires cooling the entire MH for the most part.

All of those readings were taken with a clamp multimeter on the positive cable between the batteries and disconnect switch. I too was surprised at the A/C draw. I was getting about 12 amps solar late afternoon today... which means I can run two MaxxAir fans pretty much off solar during the day, and negligible power use at night.

I'm not planning on using A/C off batteries with this setup... I think the battery bank is too small. The intent is pretty much everything but A/C. I may add another 100Ah at a later date.
