I agree on the trailer. I should have been more specific. I am an excavating contractor looking to cut fuel costs. One way would be to pull a small pickup behind a large piece of excavating equipment, usually on back roads for less than 15 miles at a time at speeds less than 20 mph, so that the operator would have a 4wd pickup at his disposal if he needs it. This would eliminate the F-350 4wd diesel and its driver that we usually have follow the equipment operator to new job sites.
I'm just looking at options. Desperate times call for desperate measures. I just knew that people pull vehicles behind RV's all the time and I wondered what was possible.
