Info on suv rental

I live in IN. We are headed to AR in October (5 of us). I have just a standard cab truck now that only holds 3 people can fit into. I`ve been looking for a rental places that rent`s suv`s or vans. And they all say they don`t rent suv`s or vans that you can toll with. I just have a 17` boat nothing heavy. I know I could rent a boat down their but would like to take mine its set up the way I like for it to be. Just wondering if anyone knows a major rental place that will let you toll a boat with. I have already tried Budget and Enterprize.

Is it that they have a policy against towing with their vehicles or that the vehicles are not set up for towing?
If the latter you can rent a tow bar from U-Haul.

It was for Insurance reasons from what they told me.

Try a car dealership..The ones aaround here will rent them as needed...if ya got a friend or someone or even if u know a car dealer ask them...
