needing opinions fella's on dog boxes!!!

[grunterhunter28]

guys me and my family are bout to build some dog boxes at our shop what kind would yall prefer? were thinking about building a box that can be used in the summer than transfered to a winter box as well that way your getting the best of both worlds rather than buying to different boxes.. not sure how its going to be rigged up but were going to try and make it stand out and look good but also keep it at a decent price what yall think?
