Reliability of coaches using DEF

Midasman, you have legitimate concerns. As with anything in life that has a motor, it can fail or any of it's components.

Our DPF Monaco Dynasty gave us no trouble in the emission dept. We drove it almost 70,000 miles in 7.5 yrs.

We now have a little over 11,000 miles on our new coach. So far, no problems in the emission dept.

Sure, something can happen, I don't lose sleep over things I cannot control.

Safe travels,
MM.

I guess my concerns have been:
1. Electronic glitches even if the other equipment is operational
2. Half way to Colorado, or climbing the Million Dollar Highway and HELLO Limp Home Mode
3. Mr. Cummins dealer says "Hey buddy, you need a $15,000 DPF replacement
4. Or worse yet, the dealer tells you "Uh, we're just not sure what is wrong...
Remember, my concerns have arisen due to the dealer's inability to repair a long haul Dodge Cummins diesel with very great loss of ability to generate REVENUE...
I must, however, acknowledge that unexpectedly, no one with a new rig has come forward with campfire HORROR stories about emission nightmares.

The diesel will go into limp mode under a few conditions - DEF fluid depleted and all warnings ignored. DPF full and no way to purge. Probably a few other items - maybe water in fuel.

What are you two wanting? In both cases, something needed to be removed from the fuel in order for the clean-up to work, on a extended basis. Gas, was lead, diesel, was sulfur. Problems, gas, valve seats and valves did not like the anti-knock replacement for lead, which is also poisoning our ground water, which the oil companies tried to tell them, but oh well. Problems diesel, removal of sulfur, which caused leaks and some loss of performance/mileage. The fix, different material for seals/gaskets in the fuel system. These are the facts that I know/experienced, if you do not like them, I sorry. Just like the "Laws of Physics", I cannot change them. If you do not agree, fine, unless you subscribe to the theory of if you repeat an old wives tale enough, it becomes fact.

I see you are stuck in the past. We are talking about regen of the exhaust. The NEW systems added to the current production diesel engines since 2007.

You said that 'regen' would effect hill climbing. Did you just pick that our of the air?

Tyoungs... maybe Wildmanbaker will respond to us.

MM.

"tyoungs".....your comparison made perfect sense and was probably the best example that could be given!

Tyoungs, I was responding to Wildmanbaker. I understand what you are saying.

I was responding to Wildmanbaker also, guess I should have "quoted" his post - did not mean to point my response at you, just responding in the string

Although RV'rs do not have much trouble with DPF's and DEF I would never use the hundreds of thousands of OTR trucks as an example. They have lots of problems. Big fleets buy say 1300 trucks when they need 1000. That is the only way they can have 1000 running trucks. The other 300 are either waiting for parts or sitting until the mfrs. find a fix. Even users of Sprinter diesels have troubles. The only reason MH owners do not have troubles is that we do not drive very many miles. remember that OTR trucks do at least 150,000 miles a year. That would be 25 years for a MH. Maybe in 10 years the mfrs. will have things fixed.
