Only stored an RV up here 1 year but would offer the following based on storing other vehicles in AK for several decades:
- antifreeze / pink stuff in the RV system is probably the only requirement.
- Covers are a mixed bag. They can move around and create scuffs, etc and most of them, while they don't let snow intrude, are not really waterproof and don't keep snowmelt out.
- Batteries: issue is will the batteries freeze. If they have a good charge, they probably won't freeze down to -20 or so. Disconnecting a terminal helps. FWIW, I pull my remote cabin battery every year and bring it back to town. Not because I don't think that disconnecting a terminal won't keep the charge, but because it's less PITA to bring it back than to go out in the Spring and find out (after a 1/2 day trip) that for some reason, the battery was discharged, frozen, etc.
- Storage: Snow weight (presumably) might be an issue but I'd rather see XX feet of dry snow than store the RV somewhere (ahem, Los Anchorage, probably Big Lake, possibly Kenai) that gets snow-rain-snow-wind-rain with regular episodes of ice cycles throughout the November - April timeframe. If "where to drop it" is not a determining factor, might recommend Fairbanks, but (just IMHO), I'd pull the batteries in that case.
