Diesel Engine Oil Service for WINNEBAGO FORZA Most Winnebago Forza owners assume that dropping a Cummins or CAT diesel under the hood means they can coast on maintenance—that the name plate alone buys them time.

Air Brake System Maintenance for HOLIDAY RAMBLER NAVIGATOR I clear a whole day whenever air brake work comes up — level ground, the compressor plumbed in, sockets laid out within reach and nothing else on the schedule.

Air Brake System Maintenance for ENTEGRA CORNERSTONE Skip air brake maintenance on an Entegra Cornerstone and you’ll eventually face either an expensive mobile technician visit or a roadside emergency where your stopping power simply isn’t there when you need it most. That’s not hyperbole — on a 40,000-pound coach, compromised air brakes aren’t just inconvenient, … Read more

Diesel Engine Oil Service for HOLIDAY RAMBLER NAVIGATOR I can pull the dipstick out of a Holiday Rambler Navigator’s engine right now and show you exactly what skipped oil service looks like—a thick, tar-black paste coating the stick, metal particles visible to the naked eye, and a smell that tells you the oil broke down … Read more

Cooling System Service for ENTEGRA CORNERSTONE I’m bent over the radiator shroud with a coolant hydrometer in one hand, watching the fluid level drop as I tip it—the antifreeze is murky orange instead of the bright red it should be, and that tells me everything I need to know. The previous owner either ignored the … Read more

Diesel Engine Oil Service for ENTEGRA CORNERSTONE A shop quoted me $1,200 last month to handle the oil and fuel filter service on a customer’s Cornerstone – labor alone, no parts.

Air Brake System Maintenance for ENTEGRA ASPIRE Most Entegra Aspire owners treat their air brake system like it’ll handle itself—until it doesn’t. You ignore the annual cartridge swap, skip the moisture drain cycles, and assume that as long as the brake pedal feels firm, everything’s working.

Diesel Engine Oil Service for ENTEGRA ASPIRE What’s the difference between a diesel that runs smooth at 150,000 miles and one that’s throwing metal into the pan at 80,000?

Slide-Out Hydraulic Service for ENTEGRA ASPIRE I was three weeks into a stretch across New Mexico, pulled into a dusty BLM site near Chaco, and went to crack out the bedroom slide for the first time that trip. It inched forward like it was moving through molasses, made a sound like a wounded animal, then … Read more
