So why don't all of you just take out your shower and install something that would make sense to you? Wow...
Cuz for most it's not an every time thing. And it's there if you ever need it. There's probably things on your unit that use rarely or not at all.
Other reasons: Time. There's 3 of us, one shower. If we are trying to get somewhere more quickly, we'll use the camp showers. Or if nobody wants to wait. For example, when we beach it the guys will use the camp showers and I'd use the MH shower. Also, when my hair was very long it was much easier to use the camp shower. Sometimes we'll disconnect the night before an early departure so we aren't making a lot of noise in the a.m. and use the cg bathhouse in the morning. And sometimes just because.
