I am trying to find out the specs of the leaf springs for my 2002 Coachman 107 Sport pop up trailer. I have tried calling Coachman but they are no help since all of the old records are gone due to the sell of the company. I have called Dexter the manufacturer but they have not been any help either... Anyone know where on the web those type of specs may be found? Does anyone archive that type of information? Thanks for the Help....
