OK Gentlemen: I am refurbishing a trailer. It was originally dual axle but I have the option of converting to single axle. Weight is not a problem as it will only be carrying 2600 lbs (net) Tare: 1,000 lbs (single axle), Gross: 3600 lbs.
Given the same boat on it in either configuration, obviously the dual axle will have at least a little more drag and weigh say 150-200 lbs more, BUT, how much will it reduce the gas mileage of the tow vehicle? Drastic--like 3-4 mpg. --or slight like 1 or less mpg? Would there be any benefit to staying dual axle? Never had a dually before.
Anybody have some actual valid comparisons? Thanks.
