If you want a hot shower, this is the way to go. I don't have a heater for mine, but they are sweet!

I remember when these first came out...West Marine was selling them to small boat owners...but they did not have a heater feature. I'm also wondering if you can adapt your onboard air to provide pressure for the field fill kit to eliminate the bike pump...I might have to get one of these...I'm starting to tire of baby wipe baths prior to rolling into the sleeping bag when I don't have my trailer...
