Anyone use the home made rear ramps on the front? Curious to know if the angle of approach is to steep etc....i need to do the timing chain and the ramps seem like a simple and safe solution for raising the front.

I think it is much easier to just use 2x10s. That’s what I used and it’s fine for front or rear.

I used to have the Rino ramps. Last time I used them was when I backed down
and I gave it a little too much gas and shot the ramps 25 feet out in front
of the coach, I was on the street with a fairly steep grade so I had to
give it some gas to back down off of ramps.

My professional opinion goes like this:
2 ea. 6 ton rated steel jack stands for the front, positioned on the frame
where the front clip bolts to the frame rails. (Not Harbour freight)
4 ea. 3 ton rated steel jack stands on the rear of the coach, positioned
where the cross members intersect with the side rails both before and after
the rear suspension.
This is assuming the coach is on a level concrete floor.
If you are on gravel or sod, you are on your own.

Which brings up a great question. For those of us who have to work on gravel or asphalt, the jack stands need to be placed on something. What is the best option? Plywood, 2x10s, concrete patio blocks or something else?

My approach is bit different. I have 3, 3 ton floor jacks that I use to raise my GMC. One under each bogey and one under the center of the main cross member in the front to get it up.
Then I then use an assortment of 6x6 x 36" and 4x4 x 36" timbers to make cribbing at 4 places on the frame. I also keep the jacks in place for extra security.
Somehow I don't trust jack stands alone when I'm crawling around under 6 tons of GMC.
By the way, Harbor Freight has upped their game. The floor jacks I use are new from Harbor Freight (got them on sale last year) and they seem to be of higher quality as opposed to what they sold in the past.

With them, I can raise my GMC almost 2 feet.

Quote: I then use an assortment of 6x6 x 36" and 4x4 x 36" timbers to make cribbing at 4 places on the frame. I also keep the jacks in place for extra security.
Actually the timbers I use are 24" long instead of 36". I like to use them when I have all 6 wheels off as I did last year when overhauling the front and rear suspension.

I don't have an answer, but I have some observations.
Sometimes I have to jack a coach out on the gravel in front of my barn. I found that jack stands that have feet will punch through 3/4 plywood.
Jack stands placed on dimensional like 2*6 or 2*8 can cause these pieces to tilt on the less-than-solid surface. When I have to do this, I now use 4ea 2*X across each other. That way the tilt goes away.
I still would prefer to jack on the concrete floor of the barn, but that is not always an option because the door is too low for most coaches.

I would not trust a jack stand on gravel. Period. If you must work over
gravel (I feel really bad for you) I would only use solid wood cribbing.
Ideally stacks of blocks cut from laminated wood beams as they will not
split. If laminated wood scraps are not available then solid wood blocks
laid flat so load is parallel with grain. Do not use blocking with any
cracks present.

I have 3/8" pieces of aluminum plate that I use to support jack stands and
floor jack when I have to lift the coach on dirt or gravel.
