You must mean 20 lb/in. Their site lists an 8' cabover as 1740 lbs wet or about 18 lbs/in. The Tundra Long Bed 5.7L V8 has a maximum load capacity of 2000 lbs which is marginal but there are lighter Alaskan versions that look like they would work.suntinez said:When I talked to the nice people there about maybe doing a custom shell, they told me 200 pounds/inch. Wow. Since I have a half-ton truck (07 Tundra) with a longbed (8 feet), it took the Alaskan out of the picture for me.
