I'm going to be getting a new enclosed trailer real soon. I am considering a 7x21' v-nose with rear and front ramps, hopefully w/front ramp on curb side. I will be using this trailer for snowmobiles,quads, and lawn equipment, my question is what would you go with the steel or aluminum frame trailer? Both have 3500 lb axle's, the aluminum weighs 1860lbs, which would be a plus. The aluminum lists for about 4800.00 before taxes. Thanks in advance.
