I just sold my truck and would like to make a minimal investment to be able to carry 5 bikes on a 5x8 utility trailer. I already have a hitch mount 4 bike rack which works okay but I specifically wish to use a trailer because I am also towing a child trailer and don't have room in my jeep for the humans plus the gear - so I need the trailer. The floor is metal grid but I can easily put in a wooden floor to mount stuff too. I'd rather not buy a few hundred dollars worth of truck bed mounts from Yakima since I need 5. I also do not wish to remove front tires. I'm thinking there must be an inexpensive way to do this. Something like a bike rack that you see in front of a school or commercial building that is mounted to the trailer and then some way to secure the rear tires. Any ideas?
