Your truck will be fine with a 4700 pound trailer. We towed our 31' TT weighing slightly more than you are looking at. We towed it with a 2005 and 2015 Half ton Silverado. The 2015 is night and day difference in towing ability with the 5.3, 6spd and 3.42 gear compared to the 2005 with the 6.0, 4spd and 4.10. Fuel economy is improved as well.. I run 60-65 mph and let everyone else fly by doing 80 plus. A properly set up WDH will have a significant impact on your towing experience. Good luck with your search.
