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. We break down the latest announcement from the EPA, what it really means for diesel emissions systems, and why rumors about DEF going away aren’t exactly accurate. 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

In episode 403 of the RV Miles podcast, Jason and Abby share spring RV prep tips that go beyond flushing the water system, including doing a nearby campground “spring shakedown” to wash the rig, check seals, test smoke detectors, and more. Abby explains RV Miles’ rebranded, curated newsletter now publishing four times a week (podcast, news, national parks, and a weekend “Road Signs” edition) and, in the tank segment, they discuss a planned 2,300-site RV park near Abilene, a cougar under an RV in British Columbia, Abby’s bread-baking mishaps, and a recommendation to read Project Hail Mary before seeing the movie.

Jason critiques an overbuilt, tightly packed campground near Iowa City, Abby calls out daylight saving time, and celebrates learning “piecemeal” is the correct term, and Jason fresh-tanks a new route-checking app, RV Route Finder.

In episode 400 of the RV Miles podcast, we celebrate nearly nine years of the show, and reflect on how the show and our RV life have evolved since 2017. To mark the milestone, we're offering up five RV trip ideas based only on places we've visited: a first-time RV trip to the Black Hills/Badlands, a spring wildlife-focused Yellowstone trip, scenic drives with Durango as a base including the Million Dollar Highway and Mesa Verde, a national parks power trip linking Grand Teton, Yellowstone, Devils Tower, Badlands and Wind Cave (plus options like Glacier or Theodore Roosevelt), and a slow-travel route from Astoria, Oregon to Seattle via Olympic National Park.  *Support independent RV journalism and unlock great perks by becoming a Mile Marker 👉 https://rvmiles.com/milemarkers *Get your FREE weekly Road Signs Newsletter at https://rvmiles.com/mailinglist/ Support our Sponsors: *Check out all Blue Ox has to offer at https://BlueOx.com *Find all the RV parts and gear you need at etrailer: https://www.etrailer.com/vehicle-finder.aspx?etam=p0001 *Get 30% off your next RV Mattress at https://rvmattress.com/rvmiles with code RVMILES at checkout! *Find Liquified at https://liquifiedrv.com/ Track SSTK_MUSIC_ID  437726– Monetization ID MONETIZATION_ID AMXDXB4BX5FLHUYE 00:00 Episode 400 Kickoff 11:41 Homecoming Rally Details 14:27 Etrailer Sponsor 15:13 Trip Ideas Setup 16:41 THE FIRST-TIME RVER TRIP 23:53 THE WILDLIFE TRIP 28:35 THE SCENIC DRIVES TRIP 34:48 THE NATIONAL PARKS POWER TRIP  41:15 THE SLOW TRAVEL TRIP 47:22 Black Tank Fuel Prices 52:38 Fresh Tank: Laundry Detergent Debate 58:06 Black Tank: Protein Pressure Rant 01:02:01 Fresh Tank: Alliance RV Milestone 01:03:30 Episode 400 Farewell

Thor Industries — the world’s largest RV manufacturer — just announced a major corporate restructuring, grouping brands like Jayco, Tiffin, Keystone, Dutchmen, and others under new leadership structures. We break down what this means for the industry… and why it comes as RV stocks continue to tumble. Several major recalls that could impact RVers: • 4.3 million Ford trucks and SUVs recalled for trailer module issues • 15,000 Ford Transit vans recalled for potential brake failure • 3.2 million Weber grill brushes recalled due to ingestion hazards • Nearly 20,000 Trek electric bikes recalled over rear wheel separation risk Plus, 19 Washington state park campgrounds could close or see reduced services due to budget cuts, while Texas opens its first new North Texas state park in nearly 25 years — Palo Pinto Mountains State Park.

This week we dig into a viral RVTravel.com poll asking: How well built is your RV? The results surprised us—and they raise a bigger question: if so many RVers say their rigs are “well built,” why does the industry’s quality reputation feel so rough… and why can’t buyers easily choose truly better-built options? Then we’re joined by Geneva Long, founder and CEO of Bowlus to talk about reviving a nearly-forgotten 1930s aviation-inspired aluminum travel trailer and turning it into one of the most interesting luxury RV brands on the road today. We get into what “built like an airplane” really means, why lightweight doesn’t have to mean flimsy, and why Bowlus may be uniquely positioned for the future of EV towing. Plus: Abby’s “black tank” story about everyday kindness (and a parking lot door ding), and Jason’s take on the way people talk about travel safety in Mexico—especially Baja. *Support independent RV journalism and unlock great perks by becoming a Mile Marker 👉 https://rvmiles.com/milemarkers *Get your FREE weekly Road Signs Newsletter at https://rvmiles.com/mailinglist/ Vote for us as the People’s Choice for Best Podcast at the 2026 Outdoor Media Summit Awards: https://www.facebook.com/share/p/18EbvKNRa8/?mibextid=wwXIfr Support our Sponsors: *Check out all Blue Ox has to offer at https://BlueOx.com *Find all the RV parts and gear you need at etrailer: https://www.etrailer.com/vehicle-finder.aspx?etam=p0001 *Get 30% off your next RV Mattress at https://rvmattress.com/rvmiles with code RVMILES at checkout! *Find Liquified at https://liquifiedrv.com/ 00:00 Intro 00:31 Poll RV Build Quality 07:56 Sponsors 09:29 Bowlus Interview 10:27 Bolus Origin Story 18:00 EV Towing Future 22:38 Pricing and Ideal Buyer 23:59 Direct Sales and Growth 29:30 Mexico Travel Safety 36:07 Outdoorsy Event Boom 38:11 Parking Lot Door Ding 44:31 Book Club Pick 47:29 Episode Wrap Up
