Welcome to the forum!
What an an outstanding idea! Hooking up and going on a tour!
We have several on here that prefer stick shifts, so we'll wait and see what they say.
In the mean time Click Here
for a sample of a few of the conversations on towing with a standard shift.
Look at some of the smaller ones. If you can stand it, a smaller one with bathroom might be all you need and you might be able to do that with what you have. Not sure though. We need to hear from some who have done it.
NOTE: Occasionally we do have a bit of fun and get off topic, so forgive any non-essential information. ;)
If you use the search feature (tab on the top right of the screen) you might come up with some more info on towing with a smaller truck.
