You need to find the tow capacity of the vehicle. Horsepower by itself isn't the whole story. For example my F150 has a capacity of 7500# but can be configured with the same 300 hp motor to tow much more with a different rear end and transmission.
Consider this when you get the stats together. I towed my T-1950 for a summer with a 6cyl Nissan Frontier with a tow capacity of 5500#. That's barely 1000# over the weight of the trailer.
It was difficult to get up to 65 and maintain speed. I would get to the end of the entry ramp on the highway and merge at 35 and spent most of the time in a lower gear with the auto transmission at 4000 rpm yielding about 9 or 10 mpg on a trip. (23 mpg normally on the highway) The tongue weight was not a problem but all in all the Frontier was too small.
The F150 with a 7500# limit gets about 13 mpg towing (normally 18 mpg) and I hardly know it's back there. Someone told me once to figure towing about 75% the capacity of the tow vehicle and that sounds like a fair estimate.
PS you'll love the T-1950 !!!
