Samantha,
Understand that the 1500/150 series truck/suv tow ratings are all about the advertising. Look in the drivers door jamb for a yellow payload sticker, it will state "All passengers and cargo not to exceed XXXXlbs".... What is that amount? As it states, all the passengers, any cargo: coolers or ???, the wdh, AND the tt tw (travel trailer tongue weight) should weigh less than the stated amount. So if possible, load up your tv like you would for a longer trip, and go weigh the rig with the family to find out what just the tv weighs.
Not sure if most of the items are in your current tt or not, but if so, take a trip across the scales with that also. Weigh at least two times, with trailer and without,, to find out what your loaded tt weight is. That will give you an idea just how much your new trailer may weigh if you transferred everything over. To figure all the weights (though you may have a new tt!) you want to weigh three times as outlined in my signature link. Not sure you need to know your loaded tw at this time if buying a new rig, so weighing two times would work.
With that new trailer not sure a suv would work (most still have maybe 1500lbs of payload, don't they?), but may still be within the specs of a truck with the proper tow set up,and suspension. The newer 6spd trans trucks never seem to be lacking much on power, just the payload.
Good luck!!!
