Set of two in box.
Everything was included. Works great. Very satisfied.
Yes. These can be used wherever you need a ramp. Be sure to block the ends of the boards to prevent the ramp from moving off the top step, flooring, etc., during frequent use.
There is a chart on the mounting instructions on the box.....I went a bit shorter and no issue for me. Used 2x10x10' with my tall 4x4 trunk....dont remember the height but no issues for me.
set is two ramps....so only need one set.
My pickup is a short bed 4 wheel drive. Because I take ramps with me in the bed of the truck they are only 6.5 feet long. That means when I use them the incline is pretty steep. 8 foot boards would be much better giving a lesser incline making it easier to roll stuff up.
That would depend on the height of the tailgate, weight of the items being loaded, and how they will be loaded (driven, loaded with a 2 wheeled hand truck, etc). All of these factors need to be considered in determining the length of the ramps.
I used 10 footers and didnt scrape on my John Deere.
I did ship to store and about 3 or 4 days picked it up.
