I built a sweet 5 x 10 utility trailer with an aluminum truck box going across the front. My question is how far apart are most wheel chocks from each other for hauling two bikes? I didn't have another bike to use when I welded the first two on. Until now, I have only hauled my bike on it using the middle chock. Now I will be hauling two bikes and I put my bike on and it looks like the front wheel holder will need to be moved over. Can anyone measure there trailer and tell how far apart their chocks are?
