What Is This?

Extend a stay kit and a 20# propane bottle, perhaps with a propane stove?

My guess would have been a MH with its slide out…

that's a whachmacallit, I know a guy who's brother has one.

Are you asking about the white thing hooked up to the propane tank?

Or the RV?

Or something else?

I have a L5 instant water heater, it has hose fittings that might be used to hook up between the water line and RV to pre-heat the water going into the RV. At 1 GPM, it can warm 55F to about 105F, while at 2 GPM, the normal shower rate, you will only heat the water from about 55 to 85F, and allow using the water heater to take showers for a really long time. It looks like the white box you have in the picture.

Really hard to see. If those are white water lines it may be an 'Instant-on' water heater. That would explain the propane tank.
