I always use both. Start by draining as much as possible, and drain the HW and FW tanks. By-pass the HW tank. Then blow out ALL the lines. Then using the FW pump by-pass, pump 2 gallons of pink through the system. Open the low piont drains back into the empty pink jugs. Blow out entire system again. Then dump what pink is left into the traps.
Back in the 90s I worked at a dealer for sometime and saw quite a few dry without pink winterizations come through with split lines in the spring. The low point drains are not always the lowest point. Even if you blow the lines out, there is always some left over and it will collect in a sagging spot in the line.
I blow out the pink because the DW thinks she can taste it in the spring.

I used the dry method last year and had to replace my water pump this spring, due to a cracked and leaking housing. It'll be wet this year, but I'll blow the lines out before I pump the antifreeze..

Make sure that when you use the dry method that you can run the pump dry and get the pump clear of any water. I have done this for many years and we hit -40 temps here at times. It is true that water can still hide out in the pipes but as long as you use enough air it will be fine. Pour enough down the drains and make sure you have enough in the tanks. We have a galley tank and it has a long run from the tank to the valve and it is always full of water. I make sure that there is pink stuff running out of it before I close it up. The other 2 outlets consume a lot less of the pink stuff.

First season of RV ownership I used the dry method. Last season (second) I used the wet method. It took no more time and was in my opinion better protected using the wet method. That's what I will continue to do.

Going to stick with the "if it isn't broke don't fix it" theory. Will continue to blow lines out and use the pink. I would be to nervous all winter thinking something would freeze and with this being our new camper would be very mad at myself.

Always. Very difficult getting the red pop out of the water filter system. If you blow ALL the water out - no need to worry...

Um, thats why you remove the filter element prior to running the antifreeze through the pump.

I read that you should set the hot water heater by pass then draw the antifreeze through pipes and THEN drain water heater so that is what I did, BUT, then I turned the cold water and hotwater back to water heater before closing the bypass valve and heard what sound like a quart or so of fluid go into the water heater, did I screw up? I washed out the water heater before this all happened but made sure the water heater was drained and left plug out. I know some water stays in the water heater because the outlet is higher then the bottom of the heater I think which means there is watere left in the water heater I think.

works for me
blow everything out, put some anti-freeze thru the water pump and p-traps and toilet. i also unplug the water heater electric so i don't destroy the element by starting it without any water in it. been there done that.

One travel trailer and three motor hones and I have always used the dry method. Drain all low point drains and pull all drain plugs, open all faucets (hot and cold as well as showers) and let them drain. After all have been drained turn the pump on for a few seconds to evacuate it and you should be ready to go. I have always disconnected my ice maker and drained the solenoid valve to prevent it's damage.
I have never put any antifreeze down the drains since they have more area for expansion on both sides of the trap. I have never had any damage in these areas. This has worked for me since 1973 so I guess that I will continue to follow this procedure for our RV's.
I agree with others on here, I hate the taste of the "Pink Stuff" too.
