Weight Police??? I've never heard of such a thing on rv.net!
I will second Lyle's comment on the 3" lift. These late model trucks sit tall, and can be a problem with FW being towed nose-high. Adding the extra height only amplifies this problem.
You will want a hitch with up down adjustment for sure, and front back adj. is great too. The B&W pictured would be great, if you are an aware enough driver, to not need a sliding hitch. Rams are known to need a slider, in a short bed.
The Andersen will allow more clearance between cab and pin, not sure on up/down.
