Looking at replacing the custom built bunk trailer for my 2006 18'6" Alumacraft Navigator Deep-V boat and it seems the Alumacraft dealers around me won't/can't answer my question so I thought I'd expand my search. I was quoted an estimate of about $1500 to re-do bearings, replace tires and repair brakes so I'm wondering if it's cost effective to put more $$ into a 15 year old trailer which is heavily used or just get a similar new trailer. Thanks in advance !!
