The owners of RV Consumer group DO NOT RV. They don't own an RV and they don't spend a lot of time looking at RVs. Years ago they had friends that did give them a lot of feed back. Now, I think there are a few, but mainly they get brochures/web site info on the units and plug that into their "formulas" in some spreadsheet and come up with 'ratings'. Touring RV Manufacturers was probably confined to Oregon and Washington (meaning Country Coach, Monaco and Alpine) but neither state has manufacturers left - I'm not sure if Marathon 'builds' in Oregon or just services, since that is well beyond our price range.
Personally, I wouldn't spend money on anything written by NON-RVers when it comes to buying an RV. The very best info about a particular brand is going to come from asking questions on an owner forum. But enough people do buy their stuff to keep them (meaning the husband and wife) going.
