I just got an "appalachian" trailer - expanded metal deck over neck ( "hayhauler" ) 20' + 4' popup self cleaning dovetail, 102". Cost 4100$. I got it "local" drove out to salem ohio to look at them. Then again to pick it up.
I am not full time- just an occasional convience hauler for my own machine. There are better out there. the structure is sound, the welds and deck are good, brakes on both axles ( if you see a manufacturer making brakes on one axle as an option- STAY AWAY ), dexter 7K slipper spring axles. This is a low end trailer- but has the features I need. Paint is cheap, the wiring is minimal- plan to rewire in a year when the salt gets into the scotchlocks. The ramps are stored in trays under the dovetail, the popup has no spring assist and are heavy.
If you use a trailer a lot- things that I could not justify for the few times I will use them you may want to think of these. Two speed jacks ( if you hook and unhook a lot if time=money) Double jacks ( if the lost 50Lb payload and cost is worth the more stable parked platform) spring assist popup, or foldup full width or three ramps to make it flat in the back. The deck over neck adds weight but deckspace when you want to keep the wheelbase length reasonable ( don't do on a shortbed).
