Similar to my
L3130, maybe a few hundred pounds lighter at most. I have a 16' 10k dual axle low boy, with brakes on both axles. It is the right weight range - I would be overweight on a 7k trailer with loader, filled tires, and something on the 3 pt. So you will probably find yourself in a similar boat weight-wise.
The length is a big problem. 16' is short for this. I can fit it on (see my avatar) but there is no room to move it around for balancing the tongue load, so I need to back it on to the trailer for best balance. I REALLY wish I had got a 20 or 22', but buying used you make compromises, and I didn't know any better at the time. If you are rarely moving it, 16' will work, but it is not optimal. If you are hauling it around a lot, I would recommend a 20 or 22' 10k dual axle, with brakes on both axles. Then make sure your hitch is rated to handle the load.
I also think this will push you into a 3/4 or 1 ton PU for safe towing. Again, if you rarely tow it, and have a 1/2 ton with a capacity near 10k, it should be fine, but if you do it a lot, or in treacherous terrain, you will want a bigger towing platform.
Trailer brands vary a lot by region. Since they are big and heavy to transport, they tend to be made regionally, and not distributed nationally so much (but some will be). Around here, Felling (MN) is big and PJ out of Texas sells a lot here too. Neither is cheap - but they seem to make quality units.
Don't go short or you will regret it!
