MY NEW MUSTANGS (new to me)

[JTS71 Mach1]

Hey Guys ; well I finally did it. As most have heard me say, I have got the most ripped and stripped 72 Mach1 left on the planet. Well being a glutton for punishinment, I purchased 2 more Mustangs. A complete but very rusty underneath 72 fast back. With near perfect interior (1 owner) and a 302 with a 3 speed stick. Also a 73 Mach1, with a 460 and c6. Between the 2 I think I can build 1 complete car out of the 3 and have a ton of left over parts to sell and recoup most if not all my investment back.
Here's the question I need some opinions on. The cars are near Indianapolis Indiana about 600 miles away. I going to try and put the 72 on a car trailer and pull the 73 Mach1 behind the trailer "Doubles". I've checked the local laws and it's not illegal. I've also seen companies that build trailers, pull doubles. In fact my car trailer was built that way as it has the plate welded to the back of it for a ball to pull the second set of trailers. I've pulled cars all over this planet. With everything from a chain, tow bars to tow dollies, car trailers to tow trucks, and roll backs. But I've never pulled Double anything??????? Hell I've seen people with motor homes do it! I'd like to know if any one has any thoughts, ideas, experience, encouragement!! As always any thoughts or help is greatly Appreciated. Now maybe Ill quit complaining about My ripped and stripped Mach1! Thanks Guys JTS 71 Mach1
