Absolutely, but so many connections inside a trailer are never going to be waterproof, such as around the converter, or one of the busses, or near any terminal strip. Conventional shrink tube adds strength and electrical
insulation to the connection too. The point was that that solder/shrink tube connector looks like a failure waiting to happen if the wire gets overloaded. Otherwise, it seems OK unless the solder doesn't have much mechanical strength either.
Sometimes products seem to be designed to solve problems that don't exist.
You should have seen me making the splices on my well pump feed wires that live immersed continuously at about 70' below the water line, and are very hard to get to. Yikes!
