We brought our new 315RLS home last night!! Still wonder what the neighbors are thinking. It's been a while since we towed any TT that it took a little getting used to. Didn't realize just how long my set up is until I went to park to get something to eat (thank God for shopping center parking lots half full!) Noticed I was getting a little sway from my TV (have wd hitch and dual sway controls). Looked close at my tires, which I was planning to replace anyhow (BTW just got the TV yesterday too) and found I had 265/70R16 when it calls for 245/75R16 lrE. Hope that will make a big difference. Need to know about winterizing as I am planning to try it out nest week for a few days but have some cold weather coming in. How long does it take to clean the system out once you have winterized? Thanksfor the info.
