Vantech P3000 clamp-on rack works nicely. Also mounted Raceline 946BZ wheels and Mickey Thompson Baja Boss tires

Aluminum so lightweight and no rust running down the truck, adjustable so I can lower them into the slipstream of the cab or raise them to put a ladder or boat or anything else up top. Best price I was able to get was by putting the item sold by user: importkamikaze on my "watch" list on eBay, then he will send a lower offer (or did for me, anyway). Hardware is all very nice, packaged well and it shipped fast. Seems like a good and inexpensive racking solution that places the weight of your load fairly squarely on the bed rails.

Wheels are Raceline 946BZ, tires are Mickey Thompson Baja Boss
