The Master Lock 1-7/8", 2", and 2-5/16" Trailer Coupler Lock # ML377KA is designed to fit most trailer couplers which use a flat lip. You will simply need to measure your coupler lip to ensure it is not more than 5/8" away from the front edge of the ball channel(see image). If you have multiple trailers you can order one for each trailer as they will come keyed alike if you order more than one.

Heating pads such as the #277-000164 are designed for 29 to 40 gallon tanks which are much larger than the tanks on your Lance 650 truck camper. My fear is that they could possibly get too hot and damage the tank. From what you describe, a solution…
