Keep your current truck. It makes no sense to just buy another truck. Yours is perfectly good and still good for another 300k. What you do right now is start making "payments" into a "truck account" so when you get enough money you can buy it outright and give the older truck to me or your son. LOL.

 

I would throw a few bucks at your current truck (if it even needs it) to take care of anything that is wrong with it or showing some age and get it into perfect working condition. There just doesn't sound like much need at all at this point. If you need a little more power, do some mods to get there. If you need more power than modding it, work on the 6.0L and bullet proof it for far less than you will for a new truck. It just isn't worth spending that kind of money to drive less than 5k miles a year. A built 6.0L with studs, a decent head gasket, either a full delete or upgraded EGR cooler will run well. You can have some fun with a 6.OhOh with a little bit of work on them. I also happen to know of a mint white one that is for sale right now from legendary memeber here Gigger

A gasser is an option, but you run into problems with ethanol sitting for that length of time as well. So unless you have access to non-ethanol blended fuel in your area, that's just as much as a challenge. I'm not trying to sart anything with the gassers, but towing in elevation with a gasser is not the same with a diesel. It just isn't. I've done both and will not go back.

 

what purpose would this serve on your lawn? I hope that's not a stupid question!

 

Yaaa lol, I just copied that for the info on the shelf life, no idea if I would use it for my landscaping

 

Got 6300 miles on my 2012 6.7. It gets rarely driven and sometimes sits for a couple weeks. No issues yet except a DEF heater in the tank but I don't believe that's related to not driving it. Prob gonna end of having one of the lowest mileage 6.7 in the country hah.

 

You've got me beat and I don't drive mine much either! My 13 has 7800 miles on it. Generally I may drive it once a week, unless I need the truck or we go somewhere over an hour away. I bought this truck with the intention of keeping it for the long haul, and a gas engine that gets 10 MPG wasn't going to cut it. Mine doesn't get stellar mileage, but it's better than a gas truck, I don't care if diesel costs more. I drag my trailer around when I need to, drive it anywhere and get decent mileage, haul anything in the bed I need to.

I drain the water separator fairly regularly, changed the oil once so far and that been it. Try to get it out and drive it a good distance once a week. Met two buddies to go mountain biking yesterday, and one asked me if I really needed the dually for my 30lb bike. I sure didn't buy it for that, but driving it puts a smile on my face so why not!

 

Update. I just came off a 2-week West Coast vacation in our 5ver & realized there's no way I'd be satisfied by the 6.2s capability towing where I do. My truck was working its *** off & the 6.2 has less to work with than what I have now. If I get a new rig it's gonna have to be another diesel & I'm just going to have to make it work (DEF situation).

 

Keep your truck brother! Haha, just kidding, it's your truck do what you want. I will recommend the 6.7 if you do go for a new truck. The new 2015s have a bigger turbo and make more power not that you REALLY need it. Post a pic of your rig, lets see it!

 

DEF is a non issue. Fill it at oil change, done deal

 

IMHO, You only live once - get the new truck and enjoy it when you do get to drive it.

Once you go Diesel you'll never go back to gas. (in a truck anyways - I love diesel cars too, but those are hard to find here in the U.S.)

BTW - Gigger's 6.0 creampuff will never be for sale since he can't seem to get the 2015 he ordered to come in.

DEF is made from urea and that is used in fertilzer... So technically yes you could dilute and put it on the grass.

Think of the truck like an RV or a fiver that is only used on summer vacations. For most people they don't get a lot of miles on them either... And a lot of those are a whole lot more than a new 6.7....

 

It's odd some say keep your truck, you don't want payments,etc. We'll my father in law has been retired for about 18 years now and he's had 3 new trucks during that time and my mother in law has had three new cars as well, it's there money they spend it as they see fit as you will do as well I'm sure.

FWIW I pulled my 34' 5th wheel(11,500 lbs) with my 2002 V10 which had much less power than the new 6.2L's. Just curious, have you rode in one that was pulling that weight?
I made the switch to diesel due to pulling my trailer 6,000-8,000 miles a year, and my right foot weighs about 50 lbs. honestly I just always pull about 75-85 mph and the gasser was a struggle to do that. Also, and to be most honest, I was tired of getting beat in truck pulls by diesels, granted it took tuned trucks to do it, so I used the towing excuse for my wife to go along with it.

I suspect as I get on in life I will slow a bit, and also won't be doing my own work on the truck, so I'll probably be going back to gas, and maybe a supercharger but still gas.

 

Urea is a good source of nitrogen. Should be good for the lawn if the concentration isn't too high.
