You say your requirements are to install it into a campervan, so the vehicle mounted heat exchangers wouldn't be that practical.
Have you considered a "portable" style water heater such as the Coleman gas fired hot water heater with shower attachment.
Most people would use a shower tent, adjacent to the camper.
The pickup hose can be inserted in a bucket, or creek if you are close enough, or probably attached to a storage tank if that is your preference.
