I see trucks with TCs towing all of the time. The biggest issue is whether the hitch will work or not. If you have an extension, the hitch has to be strong enough to handle the tongue weight at the extended distance.
You also aren't describing what TC you are hauling and what that weight is but for payload, you are probably going to be ok.
