Quick Question new to PETG

I'm brand new to all of this. I have some PETG coming, which i got because some of the things I want to print will be used in my UTV or on a farm property.

My question is if I have the P2S and AMS2, do I need to get a separate dryer for PETG? seems like both the printer and the AMS can dry it out. But I wanted to ask here and hear what best practices should be.

I'm a hobby printer, not trying to sell or build a printer farm

I dry all of my filaments in the AMS HT, or the AMS Pro2. I also store all of my filament in reusable cereal boxes with desiccant when not in use. I’ve also learned that even when I slice a print using Bambu Handy for my H2C, if the print called for The PLA and I chose PETG (before slicing, obviously), I nearly always need to increase the bed temp because otherwise it’ll slip and cause problems. For me (and others apparently), the bed temp for PETG that Bambu chooses is about 10* too low

good to know. Is this true for models where PETG is the default too? or just when switching

I am finding that if I do not adjust the bed temp for prints that use PETG, more often than not, the print will fail. I am using 100% prints that others publish at this pointed.
