Well, from where I sit, there's two ways to look at the problem.
 
1)  We're not getting any younger.  So how much is your time to rebuild your present trailer worth, as opposed to having one good to go?
 
2)  $1200 is not exactly chicken feed, and given your present situation perhaps it's better to rebuild your present trailer for a lot less than the twelve hundred for the new to you one.
 
So that's your choices.  If it were me, and i could afford it, I think I'd probably buy the one already made.  Fishing season is short and my time is precious.  Why waste it working on the trailer when you can be yelling at CB for catching all the fish?
