Review: RETURN CUSTOMER - QUALITY PRODUCT - Purchased a PROVEN trailer tongue lock this spring for our camper trailer and was so impressed with the DESIGN & QUALITY that I ordered a second one for another trailer. They are more expensive than cheap imported knockoffs but when I leave the trailer parked I am confident that thieves would look for an easier target.
