What better place to ask opinions about modifying my barn than here on an RV forum.
But seriously, its for my camper if it works.
My barn is 40' wide and 60' long. Clearance to the bottom of the trusses is 13'8". There is a 12'6" door right in the middle of the front and the rear of the barn. The trusses inside have no middle support. They were designed to work together, 2' on center, to hold up the roof, probably a 3-12 pitch.
Presently, I use the barn for my landscape business and its been great to have. But in less than nine years, I retire from the fire dept. so at the very most, I will be semi-retired from landscaping and just mowing a few yards on the side. But for the most part, the barn will be empty. No need for fertilizer, mowers, ice melt, etc.
It will be perfect for the camper. So perfect, I want to modify it soon. The idea of having the camper completely inside a structure where I can keep it set-up with power is an awesome thought. I have the camper now sitting underneath a lean-to on the side of the barn but that's too narrow to put out the slides. Its so tight, its hard to even get in the camper through the door.
So now, I have to find a way to make room for a garage door 14' tall in front and back. That most likely means modifying the trusses. I know modifying trusses like these is considered taboo. But my totally amateur thinking says it must be possible. My first thought is run an I-beam down the full length of the barn on both sides of the door. Use maybe two posts per I-beam for support. Then cut out that section of truss approximately 2' high and the length between the I-beams and brace what is left. The I-beams will now be handling the support of the trusses and the roof for the most part.
I Googled "modifying roof trusses" and a few pictures came up. I love this idea but not sure if this is possible.
I have contacted the engineering company who designed the barn and they said my only option was raising the walls and roof. When I threw my I-beam idea at them, they didn't respond. That obviously tells me they don't want to deal with my crazy self anymore.
Anyway, what say you folks? Pretty smart people here I have learned. I don't really like the idea of a sliding barn door because they're hard to get "powered" and it would cover up too much of the barn. I thought about a roll-up garage door but that still will need at least one or two trusses modified by the doors. They're about $6000 per door installed for 14' high. Not completely out of the picture but I still think modifying my trusses will be better in the long run.
Here are pics of the front door and another pic looking toward the back so you can see almost the entire truss design. The 10' door to the side will remain just as it is. Only the larger 12.5' doors will need to be replaced by 14' doors.
