Coach & Powertrain: Grade Braking
Ken Freund
May 15, 2012
I have a 2006 Winnebago Suncruiser motorhome with a gas engine and a grade brake switch to the left of the instrument cluster. Would you please explain how the grade brake works? Also, would the grade brake affect a Brake Buddy? I used the grade brake intermittently coming down a lot of mountains for... Read more »
Coach & Powertrain: Problems Using Biodiesel?
Ken Freund
May 8, 2012
During a trip in our motorhome from North Dakota to Iowa we filled the tank with biodiesel and within 100 miles the engine started acting as if it were running out of fuel. I pulled over, shut off the engine, restarted it after 10 seconds and then it ran fine again. I had to do this a number of times... Read more »
Coach & Powertrain: Leveling Jack and Engine Brake Troubles
April 26, 2012
I am having trouble with the leveling-jack-warning signal on my 1998 Fleetwood 34-foot Discovery diesel-pusher. It comes on in the motorhome with an audible tone and flashing light. This signal warns that the coach is not to be moved as the jacks are not secured. I have gotten out and checked the jacks... Read more »
Coach & Powertrain: Tow-Dolly Lights
April 24, 2012
We have a 2003 Four Winds 28A Class C motorhome on a Ford E-450 chassis. I pull a tow dolly and have magnetic lights on the roof of the dinghy vehicle. My problem is, you can hardly tell if the turn signals are working. I went to a Ford dealer and they didn’t have a heavy-duty flasher. I tried several... Read more »
Coach & Powertrain: Did I Buy An RV Lemon?
April 19, 2012
I just bought my first motorhome, a 2005 Country Coach Inspire with about 35,000 miles on it. I took it for a test drive and it seemed to be OK, but I also purchased an extended warranty just in case. As I understand it, in general, the extended warranty is supposed to cover things that aren’t normal... Read more »
Coach & Powertrain: Solution To Blowing Fuses
April 17, 2012
The problems with the Workhorse chassis brakelight circuit on a 2001 Newmar Mountain Aire and a 2003 Winnebago Brave in past issues could be the same problem I had on my 2007 Newmar Canyon Star. An intermittent fuse problem turned out to be caused by an unsecured wiring harness falling against the exhaust... Read more »
Coach & Powertrain: Holiday Rambler DIY Dilemma
April 10, 2012
I own a 2005 Holiday Rambler Imperial with a 400-hp Cummins engine. I changed the oil and did not put oil in the filter. When I cranked it, the check engine light came on. I was told at an RV dealer to disconnect the battery for an hour or two and it would erase it. Now that I have done that and reconnected... Read more »
RV Clinic: RV Cranks But Won’t Start, Intermittently
April 3, 2012
We have a 2001 Jayco built on a Ford E-450 Super Duty platform and are delighted with our motorhome. We stored the coach by removing the deep-cycle battery and disconnecting the engine-starting battery. Five weeks later when trying to start the V-10 for off-season running/upkeep, all I could get was... Read more »
Coach & Powertrain: Drivetrain Maintenance for Diesels
March 29, 2012
In the excellent article on Drivetrain Maintenance for Diesel Motorhomes in the December 2011 issue there is one point that needs clarification. You state that air filter elements should be changed when the restriction reaches 25 inches of vacuum. This is true, but it is not the usual inches of mercury... Read more »
Coach & Powertrain: ABS Light
March 27, 2012
I have a 1995 Damon Ultra Sport motorhome. Ever since I bought it in 2001, the anti-lock braking (ABS) warning light comes on, sometimes after driving it for several miles, or maybe even just a couple of miles. Once I stop and turn the engine off, then start again the light will stay off for a while.... Read more »
