Hi Sue,
Just checking to see if you found your low point drain valves and got your rig winterized. Was just checking my reg and noticed I rudely did not answer your inquiry

Dear Jim - I have the same Micro Minnie as you do and have winterized ... I think! The only thing I'm unsure of is the low-point drains under the sink and one of your comments implies you have mastered these! The examples I found on the web are valves that pop up and down but mine (and yours I think) are twist valves. Since they do not simply run along a visible line, I am unsure which way is open - parallel with the width of the trailer or parallel with the length of the trailer. Am I right that I should leave them open all winter? I REALLY appreciate any help you can give me. Thank you. Sue
