There’s a lot of confusion right now about diesel engines, DEF, and what the EPA actually changed—and in this episode, we’re cutting through the noise.

Plus, oil prices are climbing again, Buc-ee’s continues its rapid expansion, and there are some interesting developments across the RV industry—including a possible return of Winnebago fifth wheels, and a behind-the-scenes technology that could change how RVs are designed. ****************************** Connect with RV Miles:  RV Miles Facebook Group: https://www.facebook.com/groups/rvmiles Shop the RV Miles Amazon Store: https://www.amazon.com/shop/rvmiles RV Miles Mailing List: https://rvmiles.com/mailinglist Mile Marker Membership: https://rvmiles.com/milemarkers 00:00 Intro 01:25 How DEF and SCR Work 01:58 Deletes Limp Mode and EPA Changes 03:53 New Sensor Guidance and What It Means 06:16 Sponsor RV Mattress by Brooklyn Bedding 07:06 Oil Prices Hit Four-Year High 08:00 Buc-ees Expansion Plans 08:33 Winnebago Fifth Wheels Tease 09:30 REV Group New PDI Center 10:14 Digital Design Studio For Future RVs 11:27 Newsletters and Sign Off
