I currently have a 77x12 PJ utility trailer that has been in my family for 13+ years. I am looking to upgrade to a tandem axle 83" with a side gate but I can not decide if I should go 14' (will fit in most garages in the future) or should I go 16-18'? I just graduated high school so I don't have my own house or shop yet. Also, are the 5200lb axles worth the upgrade? I currently have a 60" Ztrak that I plan to get a bagger for soon and want to get a Deere W36M next spring. I have a 2010 Silverado 1500 Z71 if that helps.
