I have a 2013 Dutchstar and am having an issue with the fuel economy accuracy indicated on all of the fuel pages. It appears off by 15 to 20%. I had a 2011 with this same system that was spot on. Has anyone else had any similar issues?? John

I , don't have the economy read out on my coach, you could ask the chassis manufacturer about possible system adjustments to improve accuracy.
BUT, Having said that; if my experience with the read outs in cars & P/Us is any indication; the fact that you had one that was spot on would be a rarity.

On our 2013 DS, the fuel used display is about 10-15% less than actual at fillup time.
