One of the most important things to look at for a tow vehicle is NOT the towing capacity....don't get misled by it. The "payload" factor is what really determines the size of trailer that it can pull. Most SUVs (with the exception of the 2500 Suburban and the Ford Excursion) will be limited to 1500 lbs or less of payload. Once you add the driver, passengers, equipment, etc, that 1500 lbs is reduced quite rapidly.
To determine the correct size TT, you will need to find out it's GVWR (forget the "dry" weight) and multiply that by at least 12%. That will give you the trailer's approximate tongue weight once it is loaded up and ready for camping.
What ever payload weight you determine the tow vehicle to have(after subtracting all the other weights from it), the trailer's tongue weight can NOT exceed that weight.
Research and do you homework before making a rash decision that you may regret later on.
Hope this helps, and good luck.
