As mentioned in another subthread, rental contracts for pickup trucks often prohibit towing, and the trucks aren't even fitted with a tow hitch. If you want to tow with a rented truck, you'll need to rent from a "commercial" rental company and you'll be paying a lot more.

Even then, the rental trucks i've found that let me tow have the wrong hitch (bolted on ball of the wrong size) and don't have a brake controller meaning they can't tow my trailer.

Sounds like a hole in the market!
