We've been looking at shower systems to go with our new chitter and shower tent. I almost bought one that was $150 bucks at Sportsman's. After you start reading the fine print you realize they aren't worth a darn. Only raises water temps 20 degrees? They had another one for $400 bucks that seemed really good, but darn, $400 dollars!!! I was thinking about just building one with a deep fryer burner and finding some kind of pump to pump it to the shower. Any of you guys ever tried this? Any advice?
