Best of luck with your eyes, Butch. Must be tough not being able to see clearly.
Today I put down a deposit on a new dump trailer. Checked out 4-5 local brands, compared quality and prices, and got the heaviest duty trailer I could find. 10 gauge steel floor and walls, scissor lift hoist, two 7K axles with brakes, built in battery charger, etc. It addresses a couple shortfalls in my current trailer as well.
My old one works but I bought it used 8 years ago for $3200 and have beat it up pretty well. It needs about $2K in repairs to get it back up to top shape. Or I could sell it for $3K and put the $5K towards the new trailer. New one is $8K including tax, tag and title.
I'm telling you, it's almost impossible to lose money on a good dump trailer.
