chassis weight

[gmcbuffalo]

I was Harbor Frieght and they had a set of 6 ton jack stands which made me think If I had four of them could I keep the weight of the coach off the suspension system. So what is the weight of the chassis on a 1992 40'XL real wood cabinets and standard options?

Greg our 40XL weighed in at 42000. That was full of fuel and water.

Greg, if you have steel salvage yard close you can get some pretty cheap stands there. I have taken
some 3 ½ x 1/4 inch pipe and cut to length to stand the bus on when in the barn. If you need the
lengths, let me know. I raise mine up above ride height, so I can crawl under it easy.

Greg,

Fast Roger and I have an alternative to Dale's excelent method. We got some air over hydraulic jacks from Harbor Freight

and when the jack is under the body support points, and the center screw extended they almost touch the support point. Now you can let the air out of the system and the bus will be supported like Dale's is, or you can air up the jack and literally raise the wheels from the ground and never get under it while it is being raised. Once the jack is extended you can put blocks under the wheels, or do what you need to do. The jacks are not stands so it is best to never work under the bus with the jacks extended, but they do provide some additional advantages over stands only, and at the price they are a good investment.

When I work under the bus I just use them with the jack fully down and the screw extended so they are functioning like stands.

Those 6 ton harbor freight jack stands, if you read the box carefully, can hold 6 tons for the pair, or 3 tons each. That is 6000 pounds each.

So divide 42,000 pounds by 6000 pounds and you would need 7 of them.

Now, how to space them out so they hold the weight evenly with 7.....

Peter, we all know that your the engineer....can't you just tell us?
