I did it once, I had a 20 ft enclosed that I hauled a buddys BX23 in. I was tight and a pain to chain down but fit for 300 mile trip.
I know that they are making higher enclosed haulers theses day to fit some of the bigger UTV's in.
I have a friend that gets them in from Port Newark if the price is right. I have 2 of them and paid about 2K for each of them. Well worth it, I paint them to blend into the woods. ;)
