Tire pressure
My 2000 adventurer door plate says tire pressure should be at 70lbs PSI. The tires say 110 max PSI. Any opinions on what is good pressure? We spend alot of time on highways getting from site to site.

The max rating on the tire is the pressure you need when the tire is bearing that maximum weight, also marked on the sidewall. If that pressure were also the pressure indicated on the vehicle plate, it would mean that the tires are actually at their limits, and really should be replaced with heftier ones.
Take the total gross weight of the rig plus fuel, water, and all other cargo (preferably determined by weighing it when loaded up for travel) and divide by the number of tires. That weight should be UNDER the sum of the maximum weights on those tires. Otherwise you are in trouble.
The max pressure on the sidewalls should never be needed in real life. If you put that much pressure in 'em anyway and you aren't also loading that weight, you will have a much rougher ride than you should, and will wear out the tire treads unevenly, not to mention suffer poorer braking/cornering.
