Most of the answer is how good the operator is at slowly adding fixes until you get to your own equilibrium. It's taken me a bout 10 years to get my ancient Lance Lite (wood frame; 1842 pounds, wet; 200w solar; PD4645; no air conditioning; no oven; no microwave; all heavy objects down low) to the place where I have confidence in its ability to get to the destination. There are so many factors that are in play with your build,most of them to the truck itself.
So, the driver's experience is the determining factor on when to hold 'em and when to fold 'em on the trail. Here are a few vids of Anza taken 6 months ago: click on link to open my drop box.

Take your pick: jump right in and find out where your own red line falls.
Alright, on edit I think your camper is too heavy for hard core off-road use. Mine is right at 2700 pounds, loaded for bear. Why so light? Small tanks; the smallest; lightest; least tall; least wide Lance camper made 20 years ago. It is still sought after by folks who want the smallest footprint and still have a hard side with all the major amenities for traveling for 6 days, 6 months, or 6 years in every season, every weather, every road condition. I could not do this without a lot of trial and error at the beginning on what works off road and what doesn't.
