Yea, they are. If for example, you look at the Ford chassis that is the basis for a majority of Class C RVs, the engine tech is a good decade or two behind what Ford is putting in their new trucks and larger SUVs. Unfortunately the RV industry is one where products are built to be sold, not to be used, and what's under the hood is not a selling point compared to how fancy the interior is. When reading a review of Ford's new hybrid F-150 a couple months ago, one of the comments at the bottom of the article really stood out to me - "Ford needs to get this in their RV platform ASAP". I tend to agree that that's actually a super clever idea - most RVs already have a standalone generator separate from the drivetrain, and rolling that into a hybrid system makes a lot of sense.
