In this video i look at using T-slot channel extrusions making camper trailer doors. I was concerned about obtaining a weatherproof seal but I believe it should work. Apologize for bad resolution, first video with VSDC Free Video Editor, 10 second sound lag, etc. I’ll get better. And it was 4 in the morning….kinda sleepy…yawn.
