Hi All, this will be our first winter full timing and we would greatly appreciate any and all tips/advice you could give us for preparing the Rv - as in plumbing, holding tanks, skirting etc. We have a Granite Ridge 3100ss and both of us are pretty mechanically inclined so we can do a lot of it ourselves, like a lot of folk we need to watch our money so DIY mods would be great. I've been scouring the net so I've gathered a lot of info just nothing specific to our Rv so I thought I'd ask here. Thanks in advance for any help.
