In an effort to avoid a long trip to the dealer and having to wait all day while they winterized my Alumascape last fall, my wife and I did it ourselves. What a mistake. I missed one of three low point drains, so everything above it must have froze solid. None of the intake water valves work. The water comes gushing out, so now I'll have to take it in and have it fixed. I suspect it will cost a bunch.
I don't plan to use the trailer until October when I will haul it to a permenent spot in the RGV, texas. If the repair estimate is too costly, I thought I would just hook up the city water since that will be all I would need anyway. Any guesses as to what I'm up against. The tanks won't fill and the lines don't get any water, it just drains out somewhere above the low point.
What a bummer. Too late for you now, but that is why many of us use antifreeze in lines. It is cheap insurance.
I suspect city water connect will leak the same. If not, you know where leak is as there is normally very very little city vs pump seperate water lines.

As long as you drained the water heater, water pump and freshwater tank, your damage should be minimal. They usually split the fitting at the shower and occasionally one or two other fittings. The lines themselves rarely split. Most freeze-up repairs only take about two hours plus a few fittings.
The lines are easy to replace. They are probably push to connect which you can find at lowes or homedepot. If they want an arm and a leg for it, then do it yourself.
