I'm looking for the service manual and wiring diagram for a 1996 Bluebird QB RE. Which is the Transit flat nosed pusher. I especially need the wiring diagram right now as I am trying to track down a few issues. If nothing else a fuse box diagram would get me started. I have looked and can't...

Hello, Just bought a 02 HR Imperial with an 8.9, the AC compressor mount is missing! Anyone have a pic of theirs so I can fabricate or maybe find the correct bracket? I bet its common an many trucks, but i have no idea what its supposed to look like THANKS!

Hey all, new member here. I have a problem with my 2002 Bounder 39R. It's on a Freightliner chassis. It won't start. The engine code says Low Voltage on fuel pump relay. I've changed all the relays that say ignition that are located under the dash. There were three of them. Are there any other...

Hi all, next spring will be the time to change all my filters on my engine and i was wondering if FLTRUCKTOP may do the job as well as fleet guard ? I use fleet guard for several years but it appears that FLTRUCKTOP filters are very much cheaper, just asking, thanks.

Hi everyone, I have a 1999 34 ft Itasca Sun cruiser with the ISB 5.9 Cummins engine. I am experiencing what appears to be fuel starvation after about 15 minutes of running following cold start. The engine will start again once cooled and repeat the process under all driving conditions and at...

We have a 2022 Foretravel FS-450 with the Cummins L9 engine. On Monday, October 6th, we had driven about 200 miles from the Houston area going to Shawnee, OK when a pickup truck pulled us over. He saw fluid pouring out of the back of the MH. When I opened the passenger side service door, I saw...

Upon returning from a trip, while 2 blocks from my house, the Cummins made a very destructive bang with a loud knocking sound. I was able to very quickly get it to a safe spot and shut it off. Got it towed to Freightliner the next day. Freightliner was gracious enough to cover the tow bill...

I have a 2019 fleetwood with a Cummins 6.7 (340hp with Allison 2500) What’s the best scan tool to read/clear fault codes, monitor gauges, and force parked regen? I was thinking this foxwell hd500 https://a.co/d/h01tRDN Otherwise there’s an Ancel https://a.co/d/5HFDIwA Otherwise I read...

Airstream CLIPPER, Travel on your holiday in luxury.

$2,300 Cummins Bill on our 2022 45opp. Coolant was leaking from what appeared one of the DEF tank coolant lines. It only leaked when cold, not when warm. I called Tiffin to inquire if this was a power glide chassis issue or a Cummins issue. They said Cummins. So took it in and they fixed the...

I have a 2002 8.3 ISC with 45k miles. It has the dreaded CAPS fuel pump. My problem is I am getting fuel in my oil. Probably 2 qts every 300 miles. I have so far replaced the accumulator, feed tubes and injectors. The accumulator was first. I had no way of checking the pressure pumping...

I have a 2003 Peterbilt with a Cummins 8.3 ISC with the caps pump. I have been having issues with the truck, first problem was a break down, i scanned it out and did some testing to determine the stator on the caps pump failed, I replaced it along with the transient suppressor and the truck...

Does anyone know what my coach part numbers are for a new VDO oil pressure gauge and sensor? Trying to find part numbers is next to impossible as original gauge was replaced with a SW gauge and it doesn't show correct oil pressure with OEM sensor. Figured I would replace both sensor and gauge...

I was driving back home from a very short trip and had this sound like a truck with a serious miss was driving right next to me. I kept hearing it, only to realize it was me. Turned out to be a blown heard gasket. Simple stuff right, so I removed the old two piece Exhaust manifold and found a...

Quick question on the Onan 10K. I was attempting to clean the overflow tank and one of the attached hoses popped out. I'm not sure where it came from but it didn't have a clamp on it so it couldn't have been pressurized. Looking at the parts manual, one hose goes to the cap assembly and the...

I am in California. This past year Cummins butted heads with the State. Due to all of this Cummins made a settlement with them. However, this situation pissed off Cummins. In about April or early part of this year, Cummins told the state later....Cummins now has moved their parts inventory to...

What a fun project this was to put new brakes on this motorhome. Here’s some stuff I learned. Brakes have always been hard pushing and motorhome hard to stop. Here’s why. 1. The slides were rusted and needed lubed on the calipers. 2. The brake fluid had gone bad from lots of sitting and moisture...

I had my RV all packed up and ready to go camping, loaded the dog in, and went to start it up—but nothing. The starter's turning, but no fire. A bit of background: This is a Cummins 24v 5.9 ISB with 81K. I replaced the lift pump earlier this year, along with the primary and secondary filters...

anybody know where of if I can get another repair manual that comes in a big binder for 2003 Monaco/cayman 36' P ?? seems r=the mechanic like it, it is missing after a radiator install. Thanks.

My sister’s 1999 Fleetwood Discovery had all batteries changed out with new ones. Per the guy doing the work went to start it up and the started went out, so he also changed it out. After work was completed, my brother-in-law drove the RV home and when he turned the key switch to the off...

Seem someone wanted my binder with all the info in it that opriginally comes with the motorhome. A big white binder. Anyone know where or if I can get a replacement? Thanks in advance.

Long post, sorry! Been at this for a couple of weeks now and have no more hair to pull out at this point. I have also posted on the Cummins website Forum and think a Motorhome group might get some other suggestions. This started with no click - no crank but I was able to use a jumper wire...
