[left]There are two by fours across my trusses. I'm curious if these are just there for sheathing purposes and Roofing. It doesn't look like they are structural. I'd like to remove for insulating purposes.[/left]

I'd like to fit 2x 48inch wide aquariums into the same wall of my home office on the 2nd (top) story of my house. Here are the details: -Great access to the space behind the wall from the garage below; there is 3ft between the wall that I'll open up and the next wall (this is presently unused interstitial space). -For each opening, I plan on using a 53inch header comprised of 2pcs 2x8 sandwiching 1/2inch plywood. -Each header will have at least 2 cripple studs between the header and the top plate. -Each header will have 2 jack studs running between the bottom of the header and the bottom plate on each side. -Between the openings I'll have 4 king studs spanning between the top and bottom plates. -On the opposite end of each opening I'll have 2 king studs. Just wanted to get confirmation that the above plan is sound before I send it over to engineer. Let me know if I should provide any additional information. Thanks in advance. PS- I have the rough sill and platform worked out as well to support the filled tanks.
