Burls - I have the 2 dog box camo (it is on the web site). This is a very well built product - strong and air tight. The insulation in this box is unmatched and both my dogs stayed warm all hunting season up in the Panhandle of TX (19 degrees!) and West TX. The doors are perfect for agreesive dogs and will definitely keep them locked up when you are eating in the restaurant or away from your truck. Mr. John Faigh is a awesome gentleman and can customize the trailer of your dreams. He can put fans, ac's, vents, water, - all of it! Tell him Rick Akers (Ft. Worth, TX.) told you to call him - you will not be sorry - this really is a great box and I feel very secure having my girls in it whereever I may hunt! Good Luck!
