Your TH will push most trucks from that era to their limits.
Will it pull it?,,,,, Yes
Will you enjoy it? ,,,, Likely not. Especially if you are not someone with a bit of experience towing something of that type and size.
If you have the truck, and it already has a hitch, then yes I would do it. If you are looking at buying the truck, and having to buy a hitch as well, I would suggest you look into having the TH delivered. Even though the Ford is considered a good platform, I dont think I would buy a 15 year old truck and then expect to use it for towing a trailer that size without knowing the truck well.
