By doing this have you had to tell your insurance so they will cover the damage if it may occur...like someone hitting it in a parking lot...or a pedestrian cutting the corner and running inot it when you ares topped at a light?
I know that on my insurance my bumber and wheels are after markert and I know perm attached, but isn't things attached to hitches so call affixed and part of the vehicle..if it was a spare tire out front how would that be handled?
BTW, Nice install and I like the propane conversioan idea.
