I had a line-lok on my '69 SuperBee race car

For info: We had our coach weighed in Jan. '07 at the FMCA Indio, Ca rally. The Recreation Vehicle Safety Education Foundation (RVSEF) weighed each corner. The numbers:
Left + Right= Axle Load
Front: 5600 + 5500= 11,100 Front GAWR= 13,200
Rear: 10,400 + 10,200= 20,600 Rear GAWR = 19,500
Total Axle Load= 31,700 GVWR = 32,700
My wife and I were both aboard during weighing.
Note that the black tank was ~50% or roughly 210 lbs
The grey tank was ~70% or roughly 330 lbs
The fuel tank was at 1/2 or ~60 gals 385 lbs
The propane tank was at 70% 150 lbs
The water tank was 25% full 160 lbs
I rarely travel with anything but a "charge" in my holding tanks, so lets take that 540 lbs off the rear axle.
I usually travel with 1/2 tank of water, so let's add 160 lbs to the front.
And then there is the fuel. A full tank would add another 300 + lbs to the front axle. But that doesn't last very long so let's leave that alone.
So I could say that the rear axle is overloaded by 540 lbs, Don't know if the ~30 ft span from axle to axle with the additional weight added to the front would take more weight off the rear axle.
Although we liived in our coach 5 days a week in Seal Beach, Ca. it is NOT configured for full time. It's pretty loaded but not with all the extra "stuff" we would have aboard if we were true full timers.
Hope this helps those with a coach like ours and have not had all four corners weighed.
