Not to beat this dead horse, but reading my newest MotorHome magazine last night reminded me a little of this thread -- and many other threads that discuss importance of weighing a motorhome.
A large Class C with two slides built on Ford E-450 was weighed as part of their review, with water and propane but no passengers or cargo, and the rear axle weight was over Ford chassis rating.
Furthermore, the large motorhome was built with lots of storage but was within 580 pounds of its 14,500-pound Gross Vehicle Weight Rating. What good is all that space if you can't carry anything?
The scary part is that if this MH is purchased without first weighing it, which I'd bet most buyers don't do before closing a deal, the owner would end up extremely dissatisfied and frustrated since a "fix" for overweight would not be available.
I find it amazing that major manufacturers (it's not a Thor) can be this careless with design, and that they would build it anyway without first weighing the prototypes.
