Pmf overlapping joints

[Simple_Abound]

It's been over 3 years and over 6,000 hard miles since my first homemade camper hit the road. It rained over 2 inches that first night and was pelted with acorns. I covered it with pmf, I had no idea what I was doing, some of it looks hideous. I've had zero issues with it. I have decided to cover my second build with pmf. I'm looking for the best way to make the roofline joint look the best I can. I'm leaning towards overlapping the sides and roof 2 inches. Pictures of first build for reference.
Thank you

Another testimony to the reliability of pmf. I've had similar experience with my seven year old first build.

I would have to agree, my fenders were so chipped from gravel roads I put Herculiner on them. The pmf not one imperfection, it's been in 100 weather to 20 below weather.

It will look better if you canvas the sides first with it overlapped top and bottom, then when you lay the roof canvas go right to the edge of the roof. So you end up with about 2" of double thickness. IMHO Mine has gone 3 years out in the weather all year round and no issues to date.

When I did mine a I made a guide (just a block of wood with a piece of 1/4" ply extending 2" over the edge)and ran it along the roof, using the plywood as a guide for a (sharp)utility knife to trim the excess roof canvas. I was lifting the cutoff canvas (glue was still wet) as I went to make sure I wasn't cutting into the wall canvas. Slow going but it worked.

Same as Pat though I put a thin piece of plywood scrap below the roof canvas to cut against. Worked well. I used my wife's little fabric cutting wheel thing. I don't know what they are called but they cut very well and don't pull the canvas in the direction it is being cut.

After cutting I reapplied glue under the overlap to make sure it had plenty. And came back after a while several times over a couple hours to press it down in case bubbles were present.

I was debating where to make the seams. The seam on the roof and underneath will look cleaner.
