I'm not really sure that it's worth a lot of time and effort to increase mileage by a couple of mpg. I guess it depends on how much free time you have and how much you can do yourself. Lets assume you have a fairly local route and put 5,000 miles per year on your truck. At 12 mpg you'd burn 357 gallons of gas and at 14 mpg you'd burn 357 gallons. That's a difference of 60 gallons. At $4.00/gallon that's a savings of only $236. Yes, I know that some might consider $236 to be significant, but it only is if the cost of the mileage savings improvements is minimal and it does not increase the time or effort required to do the job. If it means you're going to be using portable ramps instead of a gate and taking the time to deploy them at each stop, or that you're going to spend a lot of time and money replacing or modifying your trailer it's probably not worth it. This isn't meant for Richard so much. I know he's pretty capable doing things himself and would probably do things on his "off time" not when he could instead be working.
