Hi Jerry -
You'd be in the right ballpark with a 17 ft TowLite. Mine is about 3500# if I don't fill the fresh water tank - 3800# if I do. A 15 ft model is somewhat lighter and a 19 ft towlite is just slightly heavier.
I pulled mine with a 2002 Nissan Frontier 6 cyl that had a tow limit of 5000#. I actually did it over a couple 11,000 ft passes in Colorado, but I was in 1st gear on the uphill grades.
I decided, since we like to go into those high places, that I needed more pull in a tow vehicle, so I got an F150. Now I tow up those grades in 2nd.
