I'm planning on building some large ramps made out of heavy angle iron. My coach's front approach angle looks to have 15" clearance at the front bumper 44 inches out from the front tire.
Using 3 x 3 x 3/8 angle iron for the ramps means the actual surface the tires will drive on will be about 11" above the ground. This is about a four to one slope, making the inclined portion about 72" long
before getting to the level top section which will be (right now) about 18" above the ground. I've got to get high enough to remove the radiator immediately, and then whatever other maintenance items I need to
do during and after the radiator work. The ramp portions will be 3 x 3 x 3/8, but the vertical members and parts on the ground will probably be 2 x 2 x 1/4 angle. It will be heavy, and over built for the
purpose.
Has anyone had any experience with anything like this? My main concern is will the back end of the coach drag when the front is 18" in the air? I suppose I can build shorter ramps for the back and use them
simultaneously, but I was hoping to avoid that. Any thoughts?

I did my radiator in the driveway with an uncut hoop. I don’t remember jacking the coach at all. Lowered entire assembly with a floor jack.

Only thing I have found the wood ramps not tall enough is transmission removal. Drop tranny with ramps and then jack up coach scary high to get tranny out from underneath.
Rear drag is hard to say. Different coaches, and what height are air bags at??
Overbuild metal if you must. But most all of us have built a set of wood ramps based on this:

Not only angle but ramp needs to fit under coach fender/running board.
These wood rear ramps are also what I use on front.

So the general consensus is that the wood ramps will be high enough for radiator removal and timing chain work?

I can get the radiator out without raising the coach, after removing the loop that holds it. Transmission will come out with a relatively small lift if you tilt it back, slide, and then forward to clear the final drive and crossmember.
