Yep, the cabinets held on this one. Occasionally I'll find a cabinet door open and much of its contents on the floor, which would be corn chips and beer cozies. I don't carry anything heavy up high and most of the 'mass' up high in the Lance is air. You can feel if you've loaded the goods up too high as the sway increases. Some of the older pop-up steel scissor hardware weighs more than the 'air' up high in my Lance. IMHO, it's an illusion that a hard side in it's unchangeable state looks heavy up high. It was a fun study to see the angle lines above and how close, or not, the tip over angle was. Not even close, but not just because of the intersection of the lines. The other salient point is the rear track of the truck with 15.5 inch wide super singles on 12 inch wide rims with a 4.5 inch backspacing. Take a look at this pic for the wheel track on the rear axle: about 6" narrower that a set of duals.

With the wider track under the major weight of the TC the tip over point angle is extended. Then again, after rolling my CJ-8 a dozen times while rock crawling, you get a feel of how far you can go and I was forcefully reminded 12 times where too far actually is. I've gone through layovers, right and left, complete barrel rolls all the way from tires to top and back to tires; a front endo where your tail comes over your head and you wind up upside down the hard way. The only roll I have not experienced, 1st hand is the rear endo where your front end comes over your head.
