Diesel and gas

Posted 07-09-2021 at 05:11 PM by Kerrieberry

Iím new to this site.
We bought a 2021 Winnebago intent 29l October, we loved it but didnít like the noise and wanted more space. 3 weeks ago, we purchased a 2022 Winnebago forza 34t.
Question, the gas rv slows down to about 50 mph going uphill.
The diesel rv slows down about 30 mph going up the same hill.
Shouldnít a diesel go up the hill better then the gas rv?
Do I have to manually change gears.
Any help with this, would be appreciated.
Thank you

    Diesel VS Gas

    I’m pretty late responding to your post so by now you have probably figured this out on your own. How fast a vehicle can climb a hill is determined by four major factors. Torque, vehicle weigh, gear ratio and momentum.

    Diesel engines generally develop considerably more torque than gas engines that are rated at the same horse power. So, if all of the other three things are equal, the diesel will easily out perform a gas engine of equal HP in a hill climb.

    Without knowing the specifics of each of the RVs you are comparing I can only guess that the gas powered one is either much lighter and or it has much more HP and torque than the diesel.

    One last note, down shifting is the key to pulling hills. My Cat7 diesel likes to run at 2000-2500 RPMs on hills. Down shifting early keeps you ahead of the curve.
