Thank you for your comment! Rexall made a great motorhome! Yes, the Fleetguard LF9009 is a direct replacement for the Donaldson P553000. Yes, synthetic blends such as Delo 400, Mobile Delvac 1300, Shell Rotella T5, or any oil with the API classification of CK-4 meets the Cummins requirement. All 3 are great oils. Feel free to reach out if I can assist with anything else.

@@mickeyj4228 thank you so much, I own a park model no engine haha and a Fleetwood gas engine so this is my first time owning a diesel. Infact is so my first time. I put 275$ worth of diesel and then the next week I topped it off earth 50 gallons of gas 🤦‍♀️😫. 835 tow bill right from the pump. Anyway thank you for you’re video I’m saving that $600 from camping world right the road and trying to do this myself. Just figured out the mode shifter thing and diagnosing the fuel levels. 7 quarts low in the Allison transmission 🤦‍♀️it said . Just bought this rig so finding out a few things. Haha

So, you learned how to check the transmission fluid level using the shift up and down arrows? That's great, just make sure the transmission is at operating temperature when checking. You'll never want to go back to a gas motorhome. Fixing the power steering hose has probably been my biggest job in 15 years of ownership.

@@mickeyj4228 I knew you were going to say that cause at first it said OL 7 which I found out met - not to temp. But after driving it a bit got it about 170 degrees it finally scanned and said OL LO 7 . Put in 3 quarts. All I had atm. Checked it again LO OL 4 quarts. Haha no wonder it was hard shifting in 1-2 🤦‍♀️
