Just purchased 1st TT...Jayco 29REKS

I'm not aware of any 7600 pound GVWR package for your truck. 4WD Supercrew 5.5' bed is 7200 pounds. I almost bought one. Max tow package which you do not have is 7650. 700 pounds dry TW will be 1000 pounds. And if you follow the owners manual of only restoring 50% of unladen weight from front axle, the rear axle will also exceed the 4050 pound rating.

Now your truck should handle well despite the ratings. Use a quality WDH and restore 100% of front axle weight.
