Hal,

Yes, I do have air pressure gauges on the OEM airbags; I'll take a look at them and post what they read. They are made in China so
their accuracy probably isn't that great. I bought a pair to replace them from McMaster Carr, they were Ashcroft and I figger'd they
were made in the USA - NOT - made in Brazil! I have yet to install them.

I should have mentioned that just before I left Houston John Sharpe and I reset the ride height to meet the manual specs. When I got
to Billy Young's place I checked it and it was a bit high on the driver side so I lowered it and both the front sides were in spec.
I have my torsion bar unloading tool with me and if time permits I can play with this at Amana. Is anyone bringing any scales?

I should have noted the following in my original message:

Under the front dinette seat I have three torque wrenches, the wheel bearing tool, another tool box with timing light, compression
gage, vacuum gage, drill set, tap and die set, and other misc tools. Then there's the six plastic divider boxes full of nuts, bolts,
screws, electrical stuff, and lots of miscellaneous bits and pieces. There's a soldering iron and a HF Dremel tool. I reckon
carrying all this crap is why the passenger side pork chop bolt is screwed in so far.

Under the rear dinette seat I have:

What's not in the picture above is the 1/2" electric impact wrench, the 1/2" battery powered drill (with three batteries), the 4"
grinder, Mapp gas bottle and small electric screwdriver.

One more thing - Double Trouble drives perfectly; if I am in the left lane of a three lane highway it will slowly creep off to the
left slowly, if I am in the middle lane it will go straight ahead, and if I am in the right lane it will creep off to the right
slowly.

Regards,
Rob

Rob,

Looks to me like you have diagonal unbalance. Passenger front and driver rear total 6560# and driver front and passenger rear total
5640# for an difference of 920#. Do you have air bag pressure gauges? It would be interesting to back off the passenger side torsion
adjusting bolt some and tighten the driver side an equal number of turns to see what that does to the bag pressures and weight
imbalance.

Hal
