I raise boers some over 200 lbs. The goat gofer at tsc cost 360.00 + tax. What i did was search auto salvage yards & bought a camper shell with sliding windows in front & sides with the back window busted out that i payed 50.00 dollars for. Then i bought a 4 x 4 goat panel & 1/4 X 3 in eye bolts with 1 reg nut & 1 cap nut & 2 fender washers. I installed wire panels over the inside of the windows & made a rear door out of wire also all for a grand total of 156.00 and 2 hours of time. I will post pics of it friday evening.
