Looking to get into Rv'ing but have questions.

Before you rent a trailer .
Make sure your Tundra has a tow package. I know you said the specs say 6800 lbs. but does that apply to your truck on the build sheet.
The reason I ask is because some vehicles ( like a Chev Traverse ) have a 2x2 receiver (hitch) and tow only 2000 lbs. The exact same vehicle with a tow package can tow 5200 lbs.
