Evening folks. I am needing 2 get a double dog crate suitable for 2 large collies, comfortable enough space wise for being in it for an hour or 2. It is to fin in a Dmax with an Aeroklas canopy. I have looked at the K9 website but the ones listed as suitable for the Isuzu have a slope at the front as if they are for fitting against back seats which seams to be a waste of space in the pickup. The boxes with a straight front don't seem to have Dmax listed. Any experience, advice would be much appreciated as they are quite a significant investment!
