Door Height?

You're going to have to measure yours. There is so much variance from trailer to trailer.

3 steps for my current trailer, 2 steps for my previous trailer, and only 1 step for my first trailer and PUP.

I like the porch level with the door, some like a step down. I my case the door is 24 inches off the ground.

As mentioned there is no standard height you will have to measure your unit.

For material list quantities, 2 feet sounds good.

My guesstimate......32"

some where between one and four steps.
