Let the debate begin. What is suitable for you? There are so many variables to consider. I don't think you can ask this question without opening a debateful can of worms.
You should probably ask yourself what you want from your tow vehicle first. Daily driver? Weekend tower? Full timer?
Again, there is no straight forward answer, just lots of opinions.
Personally I think both of those light duty trucks are going to be able to handle the load properly configured. We're going with a Dodge Ram 1500
Some will chime in that nothing less than a International Freightliner suitable.
It's still your decision. Good luck.
