Matt,
You're right - I was thinking "I wonder what the water weighs...." as I was
typing but didn't stop to calculate it. In theory, you start with 300 pounds of
water in the fresh tank and non in the holding tank, only to have it exchange
places - no net change. And generally, you don't go from full to empty on the
gas (except me, once :-). But yes, there are a lot of people that use these
things for more than just stereotypical camping. The hitch weight of a big
trailer can be hundreds of pounds. So I take it back - the rear weight can
change both between different coaches and during the use of a single coach. The
idea that someone had of just putting shrader valves on each bag, though, it
tempting - think of all the simplicity it adds.

Gary,

You have missed a basic issue with the coach. From light to heavy the back of
my coach can change by over 1000#. This is an extreme case, but 300+ in fuel
and another 300+ in water gets you most of the way there in a hurry. I often
add 4~600# in tools and material when I am working (not much anymore).

I came back from the distributor a couple of years ago with over 400# of bottom
paint (I don't want to tell you what the street value was!) along with all the
sanders, grinders and other bottom fairing gear most of it in the back bed
room.

I would not give up that automatic compensating suspension for anything.

Now air shocks in the front, that would be a plan.

Matt

What about us beer drinkers?
