Hi, You can find a welder/fabricator, in your area. He or she can make a special rack that would go into hitch receiver. If you are taking your toad, a whole new adapter hitch can be made. The 2" square tubing would have to be one piece, long enough to go into MH, that the canoe rack goes from the hitch level angled back towards the toad. The angle depends on clearence and the final height at the end of the canoe. Semi's are 13ft.6inches, high. But if you want it at 12ft., you would have to check and recheck. Now at the toad end, you can hook in, your ball hitch, if thats how you tow your toad. If you can't find anyone, I can make one. Good Luck
