Los Angeles, good luck on the local <8klbs regs. BUT read them carefully. If it truly is curb weight and not licensed weight or actual weight, then you're probably ok with a gasser 350 srw but expect to get hassled at least once.
.
If your town has the 8klb limitation, there may very well be limits on parking RV's in your driveway as well, which even without "RV" plates could get you fined for your plan to daily drive with a camper on.
Your state may license pickups with truck campers as RVs (I believe they do). And it used to be a way to license a pickup without having to get the 6 month inspections since there's no DOT inspections required on RV's. This at the expense of possibly getting a ticket for driving a "RV" tagged vehicle non-recreationally.
