Time to buy a TOW DOLLEY... advice???

[uglytruk]

I wonder if the oft seen TOW-MASTER is the right unit? I need the big (wide) one to tow a bunch of, you guessed it- Subs and PU's. Surge brakes? Electric? What brand? Tow vehicle is my 87 Sub 3/4, 6.2...
Any fer sale??? I'm in Upstate NY, near Kanada...
