I have a history in driving top-heavy wildland fire trucks (about 6k pounds high in the bed with a full tank) - sometimes in pretty nasty conditions. That being said, I am way more nervous with my truck and camper than I ever was with the fire trucks. Part of that may be the dually firetruck vs srw on my truck, but also the camper is just so darn tall. Flops side-to-side like crazy. The other aspect that not many have mentioned is the weight and sinking. Many times sand and dirt and snow that holds jeeps just fine, and may hold an unloaded diesel, are not gonna do well with an 11k lb truck/camper, especially SRW.
