There are a few different RV forums out there..
There is one set that is operated by the Affinity Group (Camping World, Good Sams, and such)
there is this one, formerly on Compuserve as Tom said a few years ago we bailed out of what does still appear to be a sinking ship (Taking a bit longer to sink than I expected though) to go with far superior software
There are the IRV2 forums
This is the best of the lot in my not so humble opinion. Big enough you can get help. Small enough you don't get a lot of noise
I saw one "Discussion" on IRV2 go to over 20 pages, mostly flaming a friend of mine for a TSB (Technical Service Bulletin) he put out which said, in short "If the customer damages it by his own actions, that is not a defect in material or workmanship and is NOT covered by warranty" 20 pages of "What are they trying to pull" (You will note that every warranty out there says something to the effect of "We cover our mistakes, YOU cover YOUR mistakes" This TSB was just a reminder of that.
We discused the same TSB here.. About one page
