From what I see, the Tundra has a 4000 lb front axle and 4150 lb rear axle regardless of the tires you currently are using. If you have a link to the axle that says otherwise, please post it.

Everything I have read confirms your findings. I would have to load up the camper and hit the scales to know for sure, but my guess would be that with weight distribution of the cabover and the ~58/42 ratio of the truck, I should still under weight on each axle. I am going to talk dry weights because wet weights are too variable and assumptions can be made, but if we all keep in mind (as I will do) I am talking dry. The truck weight is ~5640, that puts 2370 on the rear axle and 3270 on the front. With the entire weight of the camper on the rear axle (which its not) the rear axle will be seeing a total weight of 4267. since I am not finding any solid facts on weight distribution, as I am sure it varies widely depending on the truck its in. Being that the cabover part of the camper extends beyond the roof, almost to the hood of the truck, I have to think that at least 40%+ is seen on the front axle, but thats purely a guess. if I figure conservatively at 30%, that move 570lbs to the front axle, bringing the rear axle down to ~3700lbs. Given fuel, wet weights, tongue weight, it will be over what GAWR is recommended, but then again, I am already aware that I am over recommendations. the discussion has not been about recommendations. If everyone were to follow recommendations then there would either be a lot more 1 ton and bigger trucks being sold, or a lot less campers being sold.
