Any one have more feedback on the 2.25" version? In measuring my truck, I get a rake from front fender lip to rear of 2.25" with about a half tank of gas. I recently put my Bakflip on the truck and now have a full tank of gas. Now the rake is only 1 5/8". I was thinking of doing the 2.25" front, and getting +3 deavers. Should be about 5/8" high in the rear with a full tank and then get about 3/4" higher as the tank goes toward empty.
