...blinky yellow light...trailer...weighs 1000lbs...2500 lbs to pull on wheels...
As I chronicled in another thread, I towed my 20' long 10,000# trailer that goes for about 2,000# with wife (100# with 4 rolls of quarters in her pockets), the woman who used to be our children's nanny (300#+...a little heavy), her husband (250#...6'-6" easy), and our combined 4 children averaging 30# a pop. Then there's my 190# in the mix. And, of course, 8 hay bales. Not sure about the 350# estimate, but they're not that light, either...maybe 220#. I don't have loaded tires, but I have 80# cast steel weights on each rear wheel.
So I pulled another solid 1,000# up and down similar grades for about 6 miles (big neighborhood). I could feel it pulling up the slopes and could feel the trailer pushing down the slopes. I had my WD Hitch installed, so I never worried about losing my rig. Briefly considered low range on the steepest of slopes, but it pulled without a problem.
Next year, I think I'm adding a cheap brake controller box so I can have a little more confidence against some catatrophe. That's all I need is to be in the newspaper the next day.
Not to get off the subject or anything.
I endorse the $4.67 thought.
