I agree with most of the posters here, you are approaching something for which many here have knowledge you can mine information from, if you were to keep an open mind, to do so. As the pictures shows, a very unsafe condition. What hasn't been pointed out, is the configuration of the hitch will create an unsafe braking situation for the tow vehicle (truck). During hard braking, slowing in a curve, the weight of the trailing vehicle (trailer) will start lifting the rear (drive) axle, resulting in loss of braking capabilities/control and subsequent Jack-Knife condition. So, yes, very unsafe. A two axle trailer and braking helps to minimize this condition.
There is a very frequent poster on this forum that has vast knowledge and always willing to help and share;
69 Avion
He has his Avion TC in a superb pick-up trailer and tows it behind his Ford truck. I would use the search box, at the top of the page, locate his threads or send him a PM to seek his advice. He is one that has done this successfully and warrants hearing his thoughts. While you have lots of experience, it is still beneficial to listen to others, not just what you would like to hear, either.
Welcome to the forum and hope to see you back often and updating us on your plans.
