We are New newbies! We winterized our 5th wheel earlier for 1st time and are taking it on a trip next week to Florida; we live North Ga. Is there anything we need to do besides turning valves back on and turning screen around then running city water back in thru lines till they run clear? We have a tankless water heater.
 
Nope. Just run water through everything. If you have house filters, be sure to reinstall or replace as needed.

When you get an opportunity, I would sanitize your fresh water tank after the antifreeze was removed. Other than than, as Neal mentioned. you are good to go. Wait for the pink ice in your icemaker to disappear too! ;)
 
Don't forget to open the low-point drains when flushing the lines out. Otherwise, you'll get foaming from the faucets when used for the first few times. I second the point about sanitizing the lines and water tank. Most RVers will use bleach. For 40 gallons of water, you would use about 3 oz of bleach. I have a small funnel that I put in one of my freshwater hoses, pour the bleach in the funnel, into the hose, attach to a water spigot, and turn the water on. Run the water through the water lines for several minutes to thoroughly flush the lines. Don't forget the shower and the outside shower. Repeat the process for the water tank. Fill it up completely. Works perfectly if you can drive around with the water/bleach in the tank. If not, let it sit for a few minutes and drain the tank. Fill it again to wash out.

I have used this too with very good success. Amazon, $15.99 a bottle. Use one ounce per 20 gallons of water.
