Tada hot water solution

I imagine this has to come with the disclaimer that I am not recommending anyone do this, but this is a solution that worked for me.    When I took over by t@da from my Dad he had not properly winterized the camper and a number of things had been cracked due to freezing including the hot water tank which woud have been more than $1000 to fix.          I didn't even like the idea of the tiny hot water tank anyways so I ripped it out and installed something similar to the Camp Chef tank-less on demand hot water heater.    The installation was about $200.    I have had it for several years now and it works really well.     The unit does have the tendency to heat up gradually so there is a need to start mixing in cold water mid shower but it otherwise works well.
