winterizing and storage question, 88 winnebago.

[craigp1159]

88 winnebago superchief, just had a couple questions before i get ready to store it for winter.

1) how to winterize it using rv antifreeze if it doesn't have a hot water heater by-pass? seems like plumbing would be hard to get to to install by-pass kit.

2) seems like air bags lose air overtime, especially when its cold out, rv has manual crank down stabilizers, is it ok to let rv weight sit on stabilizers over winter or would it be ok just to let it sit without them down?

i also do the other things, like, parking on wood planks, putting sta-bil into fuel, filling gas tank, making sure tire psi is correct, etc. just needed a little help with those two questions, my previous rv was newer and came with by-pass option and did not have stabilizer jacks on it. thanks, craig...
