Wow. That golf cart hauler is quite the contraption. I see that more than 1/2 the weight of the cart was on the tail of the frame with that design.
The 32bkok has the bike rack that is rated for 450lbs. Figuring 4 dirtbikes and a small trailer should be under 2200lbs. Standard 10-15% hitch weight I should be about 220-300lbs hitch weight. That would be under the 450 limit of the bike rack.
Are their 5th bunk houses with outside kitchens that allow you to double?
