Not sure what your camper uses for the bypass valve or valves, but it is important to know the low spots in your bypass valve piping and to make sure it is drained or has RV antifreeze in all parts of the valves. Or else they can freeze and crack.
Normally, when I winterize, I make sure the bypass valves are back to normal after pumping the antifreeze through in bypass mode. Then when in the normal valve mode, make sure the valves have bled a little antifreeze back into the tank. This purges any trapped water in the valve body itself and or in a low lying fitting going back into the tank.
Pending which camper I am winterizing, I either use the anti-freeze method or the air blow out method. BUT, on both methods I make darn sure the bypass valves have been purged with antifreeze or air blow out.
Hope this helps,
John
