Wow , last trip we did run across a couple different places with a scale
2005 FW5000 23A Chev chassis...
Front total 3600
Rear total 7550
RF 1550
LF 1650
RR 3600
LR 3550
That was loaded with fuel , FW 3/4 full , GW 1/2, BW 1/2. and us...
So according to the Michelin's RV tire chart
I should be running 40 in front 55 rear..
That seems a bit low on pressure !
When I had the tires replaced the tire shop set them at 65 front and 70 rear (their recommendation)
This weekend we're going up into the Sierra's I-80 camping think I'll lower the tires down to 65 rear and 55 front and see how it handles the corners etc...
