TH for a family of 4 and NO off road toys - Yes - No?

I think toyhaulers are very versatile.

I will comment on your truck question.
If u r referring to the truck in your signature, hate to tell you but you don't have enough truck to pull a big 5er toyhauler.

My toyhauler, empty, weighs 12000lbs with 2700lbs of pin weight. That will put you over al of your tow ratings of your truck.

You will be ok with most any pull behind, but 5ers, you will need to stay below 33'.
