Shopping for a 3/4 ton, What fit issues should I expect?

One other thing... if you are going for SRW, try to look for a truck that has wheel sizes other than 17". You are limited in Load Index (LI) in terms of maximum weight carrying capacity for 17". 16" are becoming passe and I believe that the new norm is now 18" (I have not researched this size with respect to LI selection)... but it might give you better weight carry numbers without needing to step up to 19.5's for a relatively low weight camper on the bed.
