Hi Wayne,
I'm no expert, by far, but wanted to throw a few numbers past you. According to the 2004 Sunline brochure, the '04 T-2570 had an UN-loaded weight of 4,695lbs. and a gross vehicle weight rating of 7,000lbs. If you're like most people, you will be closer to the 7,000lbs than you'd care to admit.
You will need to know the weight ratings for your Sequoia. It's not enough, to say it will tow 6,200lbs. You will need to know the Sequoia's maximum weight rating (GVWR) and how heavy it will be, when it's fully loaded for camping (People weight included) You will then need to add the weight, that the camper puts on the truck. You will still need to stay under the Sequoia's GVWR.
After figuring all that, you will need to know the Sequoia's gross combined vehicle weight rating. That weight, is the total weight of the fully loaded truck and the fully loaded camper.... Combined.
You cannot go by the unloaded weight of either the Sequoia or the Sunline. The weights you need to consider, is the fully loaded weight.
Hope this helps..
Gary...
