Looking for Structural drawings for 1993 Toyota Winnebago Warrior

Bill Daley

Recommended Posts

 I am trying to locate drawings that show where the framing/structural members are on my 1993 Toyota Winnebago Warrior. I have been able to find plumbing and electrical drawings. I am making some conversions/additions would like to know where the best attachment points are within the coach's frame. Any help with this will be greatly appreciated.

You have way less structure than you would think. Winnebago's are made of compressed composite walls which have considerable structural strength until they get wet. There's the problem. You do have some aluminum studs in there. A stud finder is the only thing I can think of. There is an expensive one called a Walabot that lets you see inside the wall but it is pretty costly. I'm pissed at myself now. I should have gotten one when I first saw them, and they were under a hundred bucks. Twice that now

No Winnebago never published a structural layout for any of their motorhomes

Hi Bill,


Maybe it's too late but I can add somes  pictures for you. I tired down almost all my rig (92 Warrior) so I can see where frame are located. Let me know if it's still actual.

So, I made some drawings today ( I feel like Picasso🙂).



There is only the driver side. Passenger side will follow in 3-4 weeks.

So the frame follows yours rig shape. After that I have 3 vertical stud.

#1 it's right where the overcab ends:Compress_20230107_115724_4854.jpg.3d6445d2a93a8efc3629708c085dbbc9.jpg

Sorry for the mess, I'm working in my patented car shelter and outside is winter, so I'm obligated to keep all inside my rig. The coins are from the ring - I have filing that I will make a nice collection of them in the end...

#2 it's between windows :



#3 it's in the corner of bathroom:



Also there are some little pieces of aluminum sheets around the windows ore behind the cabinets, they used the 0,23 aluminium sheet for that, so it's not very strong but helps to keep cabinets and bathroom wall.Compress_20230107_115722_2578.jpg.e8ac291daac7aec9fe3383b3f4940d1d.jpg


For front and back - I had nothing solid, it's only the polyestern laminated with thin plywood. I changed that - you can see it in my topics.

For the roof it's nothing solid, they used wood.Compress_20230107_115722_2291.jpg.5188acb9e2f4eb1989268a5c40de53f1.jpg



To tear down the roof it's part of my plan - so I will see.


Now - if you don't need to tear down your walls, go carefully with the screws. Go with maximum 1/2 screws, you don't need longer than that. On the pictures you see a channel with wires, it's going from the front to back of the rig - it's marker lights. It's placed 5 to 6 inches from roof. You don't want to put a screw there 😜. The rest of the wires are on the rof and beside kitchen.

Another thing to consider is that in your rig the studs can be placed differently than in mine. To be sure that behind the wall you have stud - go with standard screw(not self- screwing), if it's stop after 1/16 then you are in the right place.

I was unpleasant surprised when on the passenger side didn't find vertical stud.



There was only the aluminium sheet, so I made a channel to add the aluminium stud.Compress_20230107_115724_4854.jpg.3d6445d2a93a8efc3629708c085dbbc9.jpg
