New OwnerNeed Tow Vehicle Advise Please

Good Evening!

We just purchased a used 2007 2720SL TrailManor, which we really love! We are currently towing it with a 2003 Toyota Tacoma V6, 4X4 that does not have a tow package on it, tow capacity 3500lbs. I don't feel that's enough pull.

Here's the dilemma: Do we try to outfit the Tacoma with the tow package ($800+ done by Toyota dealer), or do we buy a used 150 Chevy, Ford, Tundra, etc? I lean towards the mid-size TV, husband wants to upgrade the Tacoma.

Additionally, the Tacoma has an extracab which is a very small back seat, so the month long trip with grandson and dog across USA will be...tight.

Thank you all so much for your help!!!
