Use the jacks.. Take a load off the springs.
Also if for any reason you need to move into the RV for a bit.. Already ready to occupy.
One suggestion then a comment
Cut some blocks of wood. 2x12 12 (or 11.5) inches long 4 of 'em (Assuming you have 4 jacks) put one under each jack pad before extending.. Reason.
I lived in Detroit. First year I did not do that and the jacks froze to the gravel.. I got 'em lose but.. job.
2nd year I put the pads down. THEY froze to the ground but the jacks came up easily.. So I drove off. Grabbed my 8 pounder and stepped up to the wood blocks. and they popped lose like July.
After that I always padded in the winter.
Summer. Depended on where parked.. Some sites I'd lay 2x12 down to "Spread the force"
Home was where I park it. but alas the.
