Will 8 foot camper fit in 6-6 bed

I think mkirsch is just saying that realistically speaking except when there is a huge amount of overhang, the COG would be at worst the same as towing a reasonably heavy trailer/boat while carrying the camper. So, it probably really doesn't matter. Seems reasonable to me.

I will say that my black/grey tanks are at the rear of the camper, and I was able to notice my SRW driving different between having an almost full black and grey tank compared to driving with those empty. Essentially, the weight moved from front to rear as the fresh water tank was used. That's another detail that might be more impactful than the COG.
