I moved from a 1996, 10'11" Caribou with a claimed wet weight of ~3350 lbs, to a 990 with a claimed wet weight of ~3600 lbs. The Caribou was Dad's old rig and we never put it on the scales, just took the door sticker as the gospel- I know (now), big mistake...
Our first pull over the Oregon Cascades with our 990 told me there was a LOT more in the bed. We hit the scales on the same scales; our 990 is ~4600 lbs ready to camp, give or take a 100 lbs depending on family members and associated must-have toys...
