Any thing built by man will eventually fail. Judging by the pile of paper, manuals etc that came with my trailer,And the looks of the unit, the dometic fridge it was built with is still working just fine thank you very much and doing so since the build date.(Sept 1973). Both on gas and 110. That doesn't guarantee the thing wont fail the next time I turn it on, but it could also outlast me. Keep anything maintained properly and you have a better chance of it lasting, but again, no guarantees. Thats why they made tools..............Cheers.......Phil.
