Thanks George, I'm glad to finally know the narrowing is just to fit better with the box, right? But I guess you could just put the trailer together and bolt the Sears box on and go - or am I simplifying things too much?
I realize there may be wiring concerns and I might want to paint, etc. But I could build it for under $400.
Of course then there's my wife's opinion. And as all us married guys know, When Mama ain't happy, ain't nobody happy. And I think Mama has her eyes on the Bushtec Quantum GL. I have my eyes on our checkbook. she says, "We've spent $35,000 on our trike and you want to cheap out on a trailer?" I say, "It's just a box for hauling stuff around on vacation?" Of course I am getting no sympathy from my "friends" who say, "Spend, Spend, Spend... It's only money." Hey, I'm retired. I don't have a job and there's only so much money to go around.
