For 12.5yrs I have had a large Petmate Pet Porter in the bed of my truck virtually the entire time. After all these years of keeping my lab and now lab/boykin in it it's finally starting to crack badly in the corner below the door. I plan to replace it in the very near future with a large Rough Tough for a little more added protection in case we were to have an accident. I looked at the Gunner kennels but the price is ridiculous and I'm not sure that for twice the price of Rough Tough that you gain much more protection.
