We have done a lot of mods to our Palomino Gazelle G210 (yes, a Forest River product). We have pictures and descriptions on our web site at http://rvroadtrip.us/mods.asp.
Wow, you've been busy. That's a great site you have. Thanks for sharing it with us. There's definitely quite a bit of helpful information and ideas. By the way to FRF.
We added a Tornado Black Tank Rinser to the camper today and also a RainKap and Eternabond a few days ago. Here's a few pics, more details are on our web site in the "mods" area.
