Over the years,I've built plenty of ground and tower style hunting blinds. It's the most efficient way to hunt in the areas of Texas where I hunt. I've always built them out of lumber,and they work fine for a few years,but always require a lot of maintenance. There's a company in the next town over from where I live that makes some outrageous hunting blinds.These things are crazy nice,and also crazy expensive. They make an Elevated Trailer Blind that I really like,but it is priced at (Don't fall out of your chair) $8250.00 for the 6ft x 8ft Insulated model. http://ranchkingblinds.com/?portfolio=elevated-trailer-blind I looked at one of these blinds a couple times,and started turning the wheels in the ole brain bucket,and decided I can build one myself using the same materials that they are for around $2000-2500. Tomorrow,I'm going to pick up a trailer that I found for $350. It already has 4 outrigger jacks on it,plus the tongue removes for security aspects. I'll build the frame out of square tubing,cover it with 20/22 ga flat sheet metal,use 3/4" Marine grade plywood for the floor,insulate the walls/roof/under the floor. I've found a local company that sells tinted glass flip up/down windows,and also makes the same type of door that's on the Ranch King blind,and they are priced cheaper than I thought they would be. This should be the last hunting blind that I'll ever need to build,plus I can move it around with my 4 wheeler if I need to. I'll post pics of the build as I go.
