I'm not sure what the white up arrow on a green background is. When you click it a white down arrow on a red background appears. Is that the like button? If not I've not found a like button yet. Also the signature facility on the bottom of posts has disappeared too.
The problem with a lot of these guys throwing armor kits on them is that the 1114 class hmmwv's were never made to hold that much weight. An armor kit adds about 5,000 lb to the truck. The suspensions on them just can't handle it. I'm still trying to talk myself out of buying one for a trail/ hunting truck.
I would go into the grading chart and take a copy out to the shop. Inspect the boards you received and measure the good cuts and ensure that the boards you recd are actually up to the grade you paid for. If you went lower on the quality/rating to lower the price, and you recd boards that measure out to the standards set in grading, then I don't think you have a leg to stand on. if you paid for one grade but 20% of your order isn't up to that grade! dang right I'd be calling them and asking them when they would be bringing the correct lumber and picking up the crap they sent you in its place.
