I have a choice between 2 dump trailers. I have never owned one before. 2011 PJ Trailer New 5x10 single axle 5200 GVW $3k 2006 Bri-mar 6x10 tandem 7k GVW $2500 My current largest truck is a f-150 4.2l but getting an f250 before spring. I only do lawn maintence and normally haul less then 5 yards of mulch. Anything larger I normally get delivered for $50. I am buying this dump now for fall cleanups Is there any advantage to a tandem or single axle besides payload? What do I need to look out for when buying a used dump trailer?
