Where is my Glycol Tank

If you have the inside kitchen shower model, the glycol reservoir should be in the rear driver’s side under the long shelf board. You’ll need a #2 square drive screwdriver or bit to remove the screw holding the board in place.  The minimum and maximum lines are angled on the left back corner.  Use a Sharpie to highlight the lines and use a small mirror to check the level. 

If you have the CS-S (Clamshell shower) model, it will behind the cargo door behind the toilet. The Sharpie and mirror tip apply here, also. 

Which model do you have?

  Noob question. I have the same model and am wondering if the Alde is a closed loop glycol system that can be operated on heat mode only when the water tanks are drained (winterized)? Would like to have heat when boondocking In winter. What are settings on 3010 with slide controls?

@sam thanks for the info. No, I didn’t have the manual, but I do now! I am cautious about pushing buttons and turning knobs until I know what I’m doing. 

@norwood it is also helpful to be half contortionist! 

@Verna, Is the small mirror for seein' what yer face looks like while yer doin' the "contortionist" moves @Homebodyatheart mentioned? Oh, for the hard to see places.......got it.

Can someone tell me where the reservoir is for the 2018 320 S? I don't see anything in the hatch behind the toilet. Thank you.
