If you have an RV then you better get used to repairs. I have yet to find one that does not require some repair, almost every time you take it out… I have been living in my this summer and it is at least a new repair or fix, or something every few weeks. Fortunately all my stuff is minor things. small leaks with the water hose, constantly happening, so far none inside,… I think one leak caused the pump control unit to burn out and had to replace that last week…I have had a problem with the toilet since way back. So I ordered a new gasket seal. This one – the right one according to the number of the toilet, was way different than the original one? Maybe they put the wrong one in years ago and I am just now getting it done right? At least it works and seals now. I have replaced some of the faucets as they seem to wear out much quicker than your home models. I actually replaced the front sink model with a unit from Lowes that would fit and is similar to the one I took out, just a lot more solid.
oh well… Still enjoy the RV…
