The trusses are designed to give height clearence but the cross ties are still there to prevent separation of the walls. If I had any concern at all it would be side to side. I would be sure to cross brace the far end to prevent the wind from blowing the building over sideways. This should stand a considerable snow load with no problem. I would consider metal roofing to help shed the snow. I would trust this building in Vermont where I live.

I am with Ron on this. It is not the downward forces I would be concerned about first. I know they are a pain but some external braces could help prevent the wind from "racking" it.

I agree, the roof itself is VERY strong, but you can rock it around some forward and back and without the cross bracing, left and right. I will be adding some additional braces after I get the roof finished.

a nice strong 'x' brace on the back wall, and a couple '/' or '\' braces on the sides would do the trick. make the side ones so they can be removed if necessary to move large items. should stiffen the shop up without costing another arm or leg.

At this point, why don't you pick up some plywood and sheath the sides and back? That will keep those posts braced and square, keep the wind out of the place, and keep the wind from getting under the roof...You did a great job on the shed, but honestly I don't see the point without walls, a slight breeze when it's raining or snowing and whatever's under there is getting wet.

My thoughts, exactly. Not that it would help from a structural standpoint, but I would at least be attaching tarps to the side posts to keep blown water/snow out of the RV while under it.

I have a couple more suggestions. As I said I would surely x brace the end and lag bolt them as nails could work loose if the building starts to move in a high wind. I think the braces for the end to end look good as they come down almost half way but as on the end bracing I would lag bolt them as well. The part about the wind blowing the roof off. If you enclose 3 sides the wind might get in and lift the roof but if you don't enclose the sides the wind will just blow right through. I also noticed that you have used metal brackets to attach the carring beam to the top of the 4x4 posts which will help keep the roof in place. The only other issue is how well you have the posts anchored to the ground. If everthing else is hooked together the only thing that could happen is that the whole building could fly away. The structure itself looks pretty good. Just take as much wobble out of it as you can. I can't wait till you get going on the motor home again.

I thought I remembered something so I looked back and saw that you did indeed anchor the posts. You have done such a good job on the building I don't know why I questioned you. GOOD JOB
