I am buying a trailer for my atv and can't figure out what is better. I do alot of long distance driving and wan't to know if single or tandem axles are better. Also the trailers are metal grate bottombs, or should I go with wood. Right now it would be for one four wheeler but in the future it will carry two, or a atv and other equipmant. Any in put would be great. And any other thoughts you all may have.
