DEF:
Here's a few tips. As previously mentioned, the cheapest way I know to purchase the stuff is at the truck stop pumps. Roll up with the semis, run in and tell the cashier, DEF on pump #5 or whatever. It's cheaper and better than buying it in a plastic, throw away jug. Here's another tip: If you buy a couple jugs, refill them at the truck stop so you have a couple in the garage. On long road trips and hunting trips, it's not a bad idea to take a full jug along just in case. YES, you can get bad DEF at truck stops but quality control has improved. Only happened to me once in 450,000 miles of traveling in 5 years. Didn't cause me any real problems but I've heard a few stories. It is mostly a liquid fertilizer that's been used in no till farming for a long time. Mid Western farmers buy Uria by the tank load.
On a different note, the fold up seats on the CC long bed WITH the fold flat cargo area. As previously mentioned, great for throwing down a blanket and the dog bed so Pluto stays off your seats. The cloth seats seem to hold onto pet hair like Velcro. Also a really good use for that fold flat goodie: put a crib mattress down and sleep in your truck. You can also find someone to make a custom mattress out of foam pad and stitch a cover on it. You can buy all different thickness and stiffness and have it cut to your own specs. There's a business in Portland Oregon that does it. Truck drivers and hunters will do this. You can have one made for your pickup too. I'm 6"1 so it's not super comfortable but me and the wife got cozy many times and made it work, saving thousands of dollars on hotel costs.
