I've been searching though the boards here and see a lot of comments on how the PUG's help improve your A/C performance. I, unfortunately, don't have A/C in my PUP. Are there any users out there who don't have A/C and have success with the PUGs? I realize any drop in temperature is helpful in the PUP- just curious as to how noticeable it is in a PUP w/o having an A/C. Also, my Coleman Bayside has a slide out for the dining area. Should I get the PUG for that as well or just the bunk ends? Thanks!
