I respectfully disagree with this COG statement. In fact, in my Operating Manual for our AML Adventurer, it specifically states:
" Centre Of Gravity - On each Adventurer camper (left and right sidewall) is the centre of gravity sticker. The centre of gravity should be ahead of the rear axle to transfer more of the weight to the front of the truck. " The Manual goes on to provide several diagrams of the recommended Centre of Gravity locations.
Their advice is consistent with my training and experience with farm machinery equipment years ago.
It's good to have the COG at or ahead of the rear axle, but no, it does not necessarily have to be.
Especially if you have a diesel, which is already a very nose-heavy truck.
When you hook up a heavy trailer to your hitch, the COG of the load your truck sees is about four feet behind the axle. That doesn't seem to bother anyone.
If you have a regular-cab, 2WD, gas engine truck, camper COG is a lot more important.
If you have a 4-dr cab 4x4 diesel, it's less important.
The camper manufacturer has to consider the worst-case scenario.
