Welcome to the forum. Not enough information to give a good answer. Is it loosing power or just slowing down on a hill? Do you have the cruse on? Do you have it in Econ mode? Have you tried to manually down shift?Rogmix said:Diesel pusher cummins bogs down looses power going up a hill?
I worked on tugs, when I were a younger lad, 99.99 % of the time when those twin V12 149 Detroits began losing power it was a fuel filter issue. We operated under a heavy load 24/7.After a hundred and fifty thousand miles of diesel RV driving I finally had fuel filters on my Cummins ISL plug up but when it happened the engine would cut out under a heavier load climbing grades, not just lose power.
I have to agree. When you break it down to weight to HP you are moving a lot of weight with little HP. It would probably help to have some more gears like the big trucks do.I have never had a mode of transportation that doesn't slow down when tackling a hill - including my feet.
That is not a good idea; "performance air filters" pass more air through because they have less restriction. Less restriction means larger holes for air and dust to pass through.I know this is an old post, but for those of us looking for information, I will add to it.
On the rolling hills of central Texas, my 37ft 1998 Newmar Motorhome with 5.9 diesel engine would drop 10 to 20 miles per hour. I was also having trouble getting to 65-70 MPH.
I replace the stock air filter with a performance air filter and got a slight boost. Now I can maintain 65-70 on simi-flat roads and I tend to lose less speed. Still seeing 5-15 MPH drop, so I am looking for more improvement!
LOL -->> "you are moving a lot of weight with little HP"I have to agree. When you break it down to weight to HP you are moving a lot of weight with little HP. It would probably help to have some more gears like the big trucks do.
