Air Brake System Maintenance for FLEETWOOD DISCOVERY A Fleetwood Discovery air dryer cartridge runs $180–$320 depending on which OEM supplier you call, plus another $400–$600 if a shop does the job.

Air Brake System Maintenance for FOREST RIVER BERKSHIRE Most Berkshire owners run their air brake systems until something breaks, and by then the damage is already done.

Diesel Engine Oil Service for THOR PALAZZO The Thor Palazzo diesel pusher sits at an awkward middle ground — it’s heavy enough to demand real diesel maintenance discipline, but just small enough that owners sometimes treat it like a gassed-up Class C and skip intervals or grab whatever 15W-40 is on sale at the truck … Read more

Cooling System Service for THOR PALAZZO I’ve got the radiator cap off and I’m staring down into the PALAZZO’s cooling passages, and what I see tells me everything about why full-timers blow engines on these rigs.

Air Brake System Maintenance for WINNEBAGO FORZA It started as a soft hissing sound from under the engine bay—the kind of noise you almost miss if you’re not standing in the right spot.
