Thanks for all the info. I am going top check into a propane conversion and the feasibility of it. I live in the middle of Nowhere North Dakota, so I will have to see how readily available propane for fueling
I have a 1994 c3500 with a 7.4L I use to pull a dog trailer. I got it, as it is a crew cab long box, both of which I wanted to have. I don't need the power a 7.4L gives me as I will never do any heavy towing. MPG is way more important.
So in addition to maybe swapping out the 4:10 gears I am...
I am not sure of the weight of the dog trailer, it is an 8 hole. It is not quite as a horse trailer, but heavier than a comparable size cargo trailer. I am sure based on the factory code that it is 4:10 gears. A 1 mph increase isn't a lot, but then I put at least 20K a year going to dog events...
DOH typoed the 8.4L, yes it is a 7.4L. I am not unhappy getting 14mph, but do miss my 6.5TD which got me 23mph. Just looking to eek out whatever increase I can get. I know with the 7.4L it will never be great.
I have a 1994 C3500 8.4l 2wd non-dually, that has 4.10 gears. I really don't need the truck for pulling anything but a dog trailer. I would like to improve my mileage, right now without pulling the trailer I can get 14mpg, and drop to about 9mpg pulling the trailer and was thinking about...
