For me, trying to take a shower in an RV that does not have a full size shower to begin with is way too much work to make it worth it.. Again, for me... :)
The shower in my trailer is so small, my head hits the ceiling and I'm touching the wall and the curtain and with a 6 gallon HW tank, it's not like I can take a long hot shower that I can at home...
No, when I'm "camping", I take sponge baths and clean the major parts and that's good enough for me.. Or, if I really need that hot shower, I'll buy some tokens and visit the camps facilities.. Nothing wrong with them, as long as they are clean.. I do wear my water shoes however.. ;)
Anyway, for me, the need for a full on hot shower is not that important to me while I'm supposed to be 'ruffing' it... ;)
I can take a shower anytime I want, but when I'm out 'camping' for the 4 days I'm doing that, it's kinda nice to not deal with it..
To each their own and if you need to shower a couple times a day... Do it! :)
Happy camping to all, no matter how you choose to do it!
