I don’t see my self ever using the indoor sink. May happen, but I doubt it.Never even used the water features in our different campers over the years, they just happened to come w/ 'em...you could sell piss ants to a picnic the way things are now, at least you have options...
I elk hunted from a vintage Coleman popup without hot water supply. Hand washing and cleanup was a hassle. I replaced the old trailer with a 2007 Fleetwood. It has a 20 gal fresh water tank and 6 gal hot water heater. Everyone in camp loved having hot water to wash hands when needed and do dishes. The Fleetwood only has an outside shower and we do not use it choosing to have a separate shower setup. After 35 years without hot water, you'd have to fight me to take it out. I'd rather get a roof storage container, which I have, than give up my hot water supply. We also prefer not to use a toilet in the spaces where we eat and sleep.Not long ago, I got a new pop up that has a water heater. Never had one prior and never felt the need. The new camper has outdoor shower, indoor shoilet, and hot water available at the sink.
I don't plan on ever using the shower so I've been really thinking about removing the water heater and using that space as storage.
I don't want to act too rashly tho, so maybe people could help me understand what they like about keeping a water heater in a pop up.
We turn on the water heater in the evening to do dishes then shut it off. In the morning there is still warm water in the morning to wash your face, shave etc., though I rarely shave when camping.
