Hopper question
Pneumatic is my primary trailer. I sold my dry van because bumping the dock is for the birds. I know nothing about hoppers outside of the fact that they have square wheels. I don't know how much I'll use it. So it will definitely be used. 1)What structural things should I look for? 2) what is the most versatile sidewall height or size overall? 3) Does 96 or 102 wide really make a difference? 4) Is a spread axle worth the headache?
