If you're looking for another pickup, X2 on what mainah responded.
Where I typically start is to look at the GVWR of the trailer, add 10% to it and that should be the minimum towing capacity of the tow vehicle you're looking for.
A tow vehicle with a longer wheel base is also better.
For example, if the GVWR of the trailer is 5,000#, adding 10% would give you 5,500#, so I would start looking at tow vehicles with a minimum of 5,500 - 6,000# towing capacity.
There's other weight factors that could be considered, such as the tow vehicle's rear axle rating and GVWR, along with taking into consideration the tongue weight of the trailer and its loading on the tow vehicle (also taking into consideration all the other cargo that would be loaded in the tow vehicle and trailer..
But if you're looking for another pickup - like mainah said, a 1/2 ton pick-up with a tow package would do you great.
Hope this is of some help.
