The Tucson convention weigh-in showed pretty significant problems with my coach. I expected the stretch to be overweight, but was surprised at the ride height and weight imbalance that was found, because I spent many hours in 2016 working on ride height. At that time I had it pretty good, although it was about 1/4" lower all around than the low specification. At Tucson, the fronts were over an inch low at 11 3/8 R and 11 1/4 R. The RR was close at 11 3/4, but the LR was 10 7/8. The side to side balance was way off with 700 pounds heavier at LR, and 400 pounds heavier at LF. I know that bringing the LR up even to the RR height should transfer some weight to the RF. It will be interesting to see how much change there is. I know I am in for another long session of up & down and under the coach!
I have spent quite a bit of time with the manual, but have been unable to find a specification for side to side imbalance. Does anyone know if such a spec exists, and if it does, where I might find it?
We really enjoyed the convention and would really like to thank all involved in planning and executing such a great time with very informative seminars. In particular, thanks to Alex Ferrara & John Sharp who fixed my steering misalignment on such a hot day!

John,
The Body Builders Manual page 6; front allowable lateral weight variation is 250 pounds and rear allowable lateral weight variation
is 600 pounds.

I feel we got the weights about as close as possible but the left rear ride height is really tough to get perfect on most coaches. If yours didn't have the original Onan and the frame oval was visible,the measurement should be good. If you still have the Onan, the measurement should be close but not necessarily perfect. Be sure to recheck our numbers before changing things. Hal

Thanks, Rob, Didn't know about the "Body Builder's Manual", Sounds like something Jack LaLane might have written!
Hal, I will be checking pretty closely & have already done some on the way home. I have seen ride heights very close to what you guys found, so apparently my coach has settled some in the two years since we installed the Peter Huber bars & I got it leveled up. Thanks again for your work getting the coaches weighed in HOT conditions.

It was our pleasure but next time I'll be wearing gloves and knee pads-that asphalt sure was hot.
