We just bought a 2025 Gulfstream 17BH. There doesn't seem to be hardly any info on this trailer on the net. We owned a class C many years ago, and this is our first pull behind. We liked this trailer because it's a bunk house and was light (pulling it with a mini-van). I was also impressed with the esthetics of the trailer. One question though... no shower stall installed. Just plain walls. That's unsettling to me due to moisture. Any ideas on how, or what, to use to put on the shower walls? There's no shower lining. Any info would be helpful.
