Another ding story.

[Sojourner]

If you can get to the back side it might be worth a try at a push from inside. Always sneak up on it and don't do anything rash just a little at a time. You might be able to get it pushed out where it will be acceptable. I wish I could help you. The pictures are worth a thousand words. Your bus looks to be in great shape.

Lin...Is your inter wall not finish so that you can get the inter aluminum panel off to access to the damage area?
If so... Aviation Maintenance Technician such as Airbag can use a port-a-power hydraulic ram to ease it out with care. You or whoever may have to park the bus parallel to concrete block building's wall (at the corner for firm strength to avoid wall pushing in-ward in middle of the wall). After bus is jack & blocked to maintain its firm position. Add support blocking via using 2x4s to the yielded areas to the building's wall corner.

Port-a-power in between the cave in section with a piece of  ½" thick plywood with the grain aligned with the ribs & cut to the span of both vertical framing and long enough to cover the up & down of the cave-in section.
                               ____
Shape will look like this \__]

Add a piece of 1 ½" x 12" square heavy tubing vertically over middle section of plywood at the deepest cave-in area.

Plywood will flex somewhat with the yielding process. The other end of port-a-power onto a 4x4 by 6 feet onto the opposite side of bus inter wall for anchor. Using port-a-power extensions to connect in between both inter bus walls.
Stain-Less steel is much stiffer than aluminum so care must the very important factor to not to over yield it.

On the other hand...you can replace the damage section with new one from MCI or used ones. However, you must use structural type rivet...no standard pop type rivet.

Let us know what your choice is...so we can further help you to steer in the right direction.

I am so sorry about the mishap but it can be fix to please you.

Sojourn for Christ, Gerald

Lin, I withdraw My suggestion for the dry ice!  I had not had the advantage of the pictures when I suggested it.  I did not realize You had knocked down a sequia,LOL.  John

Junkman,
It actually was a very small tree.  I thought that I had merely brushed against some branches that are little more than twigs.

Gerald,
The coach is completely finished on the inside.  If I could borrow down to the outer wall, I would not much room to work.  Not to mention that I would be experimenting anyway.  I am truly amazed by your post.  It seems as if you do these repairs everyday!

At this point, I guess I will live with it.  It is really only visible if you are looking down the side of the coach.  I will see wht kind of dent man or body man I can find that would have a good plan.  Thanks for all the help again.
