Dear Joe;
Drew & Jerry are right. It's just to small.
To tow safely you need dual rear wheels to stop it and the trailer brakes. Your 261 built to 278" + mods will work with a 5 speed, but it will be working hard at it.
Too much weight to stop/start. Most 'tow rigs' today are using 400 CID + a 1 1/2 to 2 Ton chasis. The 1 Ton cab/chasis ones that I/we used in the 60-70s have proven to small as well.
It would be fine for a boat or M/C trailer.
Good luck, John M.....
