That's normal AKA I can't fix it and won't admit it LOL.
I would assume they checked all the basics, wheel balance, ujoints, driveshaft balance.
See if you can find out if they checked the balance of the wheels with a radial balancer (road forced balance). This is a type of wheel balancer that applies pressure similiar to the weight bearing of the truck while it is moving. A normal spin balancer will not pick this anomolly up.
Also, while your are moving at the vibrating speeds, will it stop if you take your foot off the aclerator or if you shift it to neutral?
