Pop the manhole lid open before unloading, or you'll end up with a tank that looks like a smashed beer can. Foodgrade tanks are great. Back it in, and go to bed. No tarps, no lumpers, no BS.
I pulled a "bathtub" truck (no baffles, 4000 gallons of gasoline) and a bathtub trailer (4800 gallons) for a while - Took it easy and never had any major problems. Had a much more difficult time with a looong-wheelbase tractor, especially while bobtailing - Tested the brakes way before an intersection to see how it would go - slid right into the intersection . . .
Most of our tankers are 6,000 and 7,000 gallon tanks and we almost always haul under 5,000 gallons . Just glad all loads are dedicated . I only run about 46% loaded miles . We need another tanker due to increased orders for stannic chloride . I was told the new tanker was FRP . I was pretty apprehensive about that until I found this site . http://www.comptank.com/frp-facts/frp-facts.html
What type of trucks do most fuel haulers have, 10,13 speeds or auto-trans? Is double clutching required when hauling gas?
