tow vehicle tires?

You mentioned the Dakota. I have a the 4.7 V-8 with the 3.55:1 axle ratio and factory towing package. The manual says I can pull 5100 lbs. I've pulled an old Starcraft pop up for several years but I'm looking for something that I could pull that will provide more room where just my wife and I could not only weekend camp but would be reasonably confortable to spend two or three weeks at a time in after I retire. I have been thinking about the 3124 or a 3326 but I would have to find a good used one. Would it be reasonable to pull one with my Dakota?

I've seen a couple that were for sale but I'd like to see one before driving several hours to buy one. I went to the Chicago RV show over the past weekend hoping to see a TM but there wasn't one there. The closest dealers are 5-6 hours away. Just from what I've read and seen on line the TM would work for me.

Not realy much of a question mostly me rambling. Thanks for listening anyway.
