Don't fear the A/C. Keep the trailer level. I used mine all last summer (NE Ohio) without a problem.
Hey I want to thank all of you for your info you are giving out on your Retros. We bought a used 2015 177, not a 177SE. We are beginners travel trailering. Love the look and style of the retros. We have absolutely NO experience so this website is helping alot and thank God for U-tube.... I am learning about Black, Gray and Potable water, I will not use the AC because of fear from what I have read here about the drainage and damage... We did not get a users manual with our rig and am having no luck in finding one, so this website helps alot there. I just read where to find the fuses below the refer...Lots to learn and I am learning alot from all of the comments I am reading here. My thanks to all and we are very excited about taking our first voyage. Val
Also, make sure it is charged and test annually for freon leaks. You should be good to go.
