I'm going to put a plug in for a great RV forum at
iRV2.com. I've been a member there for years, and they are a great group of RVers with lots of helpful knowledge of RV stuff. It is family oriented and no namecalling or bashing is allowed. It is at
www.irv2.com
I have mentioned this great Ham/Rv forum there, and several of their members who have amateur radios have joined here.
