If all you are going to do is cut an access hole for one of the drain pulls, and you don't cut the frame in two or do any other damage to any of the systems, the access hole can not void the warranty, only if where you cut the hole fell off, would that part of the trailer warranty be voided. They don't want you modifying things that could cause damage to the trailer or its systems. It would be like adding a trailer hitch to your truck that didn't come with one, can't void the warranty unless something was damaged in the process, and then only what was damaged.
