Hi everyone, I'm looking to get my first trailer, and I'd prefer an enclosed. Right now I'm looking at either a single axle 6x10, 6x12 or a tandem axle (w/ brakes) 7x14. I do a lot of landscape maintenance and pruning, but mot mowing, so I don't need a huge trailer. The issue is that I have a 2002 Chevy 1500 (5.3 engine). Being a half ton, I'm concerned about lowered fuel economy and engine/trans wear and tear if I got the bigger trailer. Right now I get about 14/mpg unloaded. In all your experienced opinions, do you know what the difference in MPG would be between the 6x12 and the 7x14? The latter weighs about 1100 more pounds. Thanks everyone!
