Before I had my trailer I also had trust issues with my tailgate and cables so I would just remove the tailgate while I loaded, it takes less than 30 seconds to remove a tail gate. As far as the ramps you have to trust what they say they are rated for, to take some of the stress off of the ramps you can decrease the angle of the ramps when loading by backing into a ditch if available. When at home I would back my Truck up to the curb in front of the house so the angle wasn't as steep, then you don't have to hit the ramps as hard when loading.
