rustyfarmall, Not feeling ambitious enough to try to remember physics and trig from 30 - 40 years ago all in one fell swoop to deal with the angles and get an exact answer, incorporate friction coefficients, etc. But I think a decent way to ball park the number is just to figure the mechanical advantage of the ramps on the trailer. Mechanical advantage for an inclined plane - your trailer ramps - is slope / height. So given that you're going to need a mechanical advantage multiplier of at least 2.8xxx for a winch which can lift 3500lbs up a 100% grade (straight vertical) to raise 10000 lbs up a grade -- and assuming the top rear of your trailer is 3 feet - you're going to need a slope, or ramp, of at least 9 feet in length ... or 10 to 12 feet to play it safe... and that's my guesstimate.
