First time de-winterizing

We bought our first motorhome this winter. It was already winterized when we bought it. It is now spring and time to de-winterize. I have watched videos on Youtube on how to de-winterize but realized all of the RVs being de-winterized were new models. Our motorhome is a 1983 Fleetwood Tioga. Is there any steps I should take in de-winterizing an older (vintage) RV that would not be necessary with a newer one that would not have been shown on the videos?

    No different. To dewinterize your water lines, all you do is run fresh water through each line until all the "pink" is removed. Traces of "pink" will cause the water to be foamy for a while. But keep flushing the line and it will all come out. If your water heater is in by-pass position, do not undo it until you've flushed the lines first. Flush, then turn the water heater by-pass back to normal position, then fill the water heater.

    If your water heater is not bypassed, the procedure is the same, it just takes longer, flush the tank until no more pink and foamy water occurs. That's all you need to do.

    Some folks will sanatize their lines next. That's another topic.
