GVH, take a look at Highland Trailer Sales in Cambridge, you can buy a brand new 4.5x10 or 5x10 , 14" wheels, 3500lb axle for $1325. brand new made in Cambridge. Made with modern wheels, nice bed, tailgate ramp or regular tailgate if you wish. You can also get a spare tire package that mounts out of the way.
I looked at Highland when researching trailers. Seems like good value for the money.
If you're planning to buy a trailer remember to include a tongue jack, spare tire with mount, a jack to lift the trailer to change the wheel and enough installed D rings or tie downs to enable you to properly secure the load you are carrying. Also include a few security items like a wheel chock and a tongue lock or chains to lock the wheels to the axle. Trailer thefts are a real problem and while these devices will not stop everyone they may encourage the grab and run guy to move on to easier prey.
