We have a 2001 International MDT and put the Morryde suspension on the front end. We were early in the development process and had problems several years later, complete replacement without any questions(including labor). The Morryde on the truck created a major change in ride and we love it.
Based on this we had a Morryde suspension put on our current trailer(New Horizons, 34', 15000 lbs), never lube axles and larger brakes(2" to 2.5"). Major difference in ride and stopping(stopping was never an issue). Disc brakes are not the only solution to braking problems. When we get our BH we will go to Morryde and have the suspension put on, never lube axle and larger brakes. Their customer service is awesome. Breakfast, lunch each day. A comfortable waiting room and when we didn't have a truck they offered us their personal vehicles for driving around..............
Regarding the comments that we need to go back to the component mfg when we have problems I would rather do that than go through a middle man and have to drag the trailer a couple hours to a dealer for him to look at the problem, send us home again and then come back. When we built our stick house we never went back to the general contractor with HVAC, water heater or electrical problems. We contacted the sub-contractor directly. We prefer not having a middle-man to muddy the waters. We agree to go back to the dealer with Heartland specific problems, that can't be avoided but for the rest it is far easier to call the sub-contractor though I think they should pick up labor to replace their "less than perfect" components when under warranty.
