Winterization 2015 Jayco Premier

After reading and watching a ton of utube vids, I think I have a pretty good handle on the process, but I have a RV double door frig without an icemaker and I'm wondering if there's any type of condensate behind the fridge?

I'm blowing my lines out first with compressed air at 30 psi, then running antifreeze through. Should I open my low point drains and run enough down the drains to see it antifeeze out the low point drains too the drains?

Or do they gravity drain only. I will be dumping a cup of antifreeze in each drain (kitchen sink, bath sink, shower, and toilet) and put a little over the toilet flapper when done.

I would not worry about blowing the lines out. Open the low point drains, close them when it stops dripping and put the antifreeze in the pump suction. Been doing it this way for 18 years never a problem
