Id have to price up what you want for suspension/decking etc.... I ran a sold axle utility trailer that I built for years,we towed 2 Banshees behind a buddie's Daewoo Lanos for 3 summers.Towed great! If a sandblasted/painted junkyard rear axle off a Chrysler minivan doesn't bother you,(Ive seen a LOT built with these) and all new stee frame / PT 5/4 decking,it could be done for right around $500,steel prices are out of sight right now. Theres so many options,its hard to give a solid price,without an actual plan....
