The truck doesn’t use def? I thought 2010 was the first year for it.

2010 was the last year for the LMM. LMM was 2007.5-2010.

2011 was the first year for the LML with DEF.

It sounds like you are not trusting what your dad is possibly selling to you?

What's his service record been like (I take it) since new? What others say aside from that really wouldn't mean that much to me.

My dad had a mechanic in the building next to his business. The truck was well serviced. I am just fearful of the unknown given I havent owned a diesel truck before, especially with all the emissions stuff I always read about. Only diesel I have owned was a TDI VW car. about 19 years ago.

I am leaning towards the truck even though I still like my tundra and I have to come out of pocket. I am thinking the longer term resale value and hopefully longer durability due to towing ~75-100x a year.

the lmm has minimal emissions and can very easily be deleted with a tune! then you will hate the tundra all together!

Have a stock '08 2500 that we regularly pull 8000 lbs with. We are located in the coastal mountain range of BC and it will hold 60 MPH on every hill and pass around here without much effort. It just hit 100k miles and never a DPF or any driveline issue for that matter. Been a great truck but it is depreciated out this year and will be going newer in the spring. The only thing I would have changed with it was going with the full size box. Ended up putting a tidy tank in this one for more range and it doesn't leave much for extra cargo space.

With all respect and with no malice towards a brand....That Tundra couldn't carry that Duramax's jockstrap. Not a fair comparison in any regard.

Ive towed 8k with a 5.7 tundra many many times and will brag they are very capable for that weight. The question the op is bringing up is if it's worth the extra cost of diesel maintenance when his load is not increasing. Yes, talk about oil change and simple DIY stuff all you want, but over all diesel fuel systems and variable geometry turbos will kick you in the ass when they break.

I was forced to upgrade to a 3/4 ton diesel because my payload increased. But if my 5.7 tundra could handle 10k safely, I would still be towing with it.

But as someone mentioned earlier, towing with a diesel does feel different, no matter what the load.

to answer the question, no there is not a huge difference in your routine maintenance. catch the oil on sale change the oil every 10-15k and your fine! where the diesel cost folks a ton of money is when they have a diesel and drive it 10 miles to work and back. the truck never has a chance to let the emissions run full cycles, or they attempt to to a delete and tune and do not take the proper precautions!

Thanks for all the feedback. I am undecided what I will do. Given that my daughter has taken over my Honda Accord a bit, I am driving the truck more daily even when not towing. I need to decide if the loudness and stiffness of the 2500HD is worth the towing benefits (or risk of high $ repairs). I will have to add ~$10 grand to get the D-Max but it has a lot less miles on it than my truck.

I am gonna think about it over the next few weeks since my father is not in a hurry.

Replace the shocks on the LMM and install some timbrens and you'll have a tow beast that will ride much better than it does currently. I bet the shocks on your father's truck are worn out and need replacing which might account for some of the "jarring". If you tow 100x a year then it makes sense to step up to the Duramax. I also think about the re-sale value on the LMM even years down the road from now if you decide to get rid of it; at least much better than what your current 2wd Tundra would fetch. But I'm also partially in the camp that you've been using your Tundra for a long time now and it's been fine towing with it so why change?

Some of the jarring may have been a result of the fact that he had air in the airbags in the rear of the truck. I would have them removed. He had airbags installed because he has a 5th wheel travel trailer that he would tow to the beach in the spring and home in the fall. (truck didnt do much towing)

Just my two cents... I ditched my tundra and downgraded by 3 years and bought a 2006 GMC 2500hd duramax to tow my 29 everglade pilot. I feel your pain in making the decision. It is not my daily driver that is why it wasn't to bad of a call. For the towing ability alone I made the RIGHT choice. I haven't put a dime into it either. Tundra was plusher though GMC has a better seat for me.

updating the worn out suspension ( shocks ) on the dmax will make a huge difference, also look at how much PSI are in the tires!

Like stated above, drop the air pressure in the rear tires.

Thanks for all the feedback. It looks like I will move forward with the Duramax. I will be doing shocks on the truck when the brakes are done, which have to be done to pass inspection

I run the 50 psi in the fronts as indicated on the door sticker. The door sticker also says 80 in the rears and I ran that all the time until maybe a year ago when I got my new air compressor set up and was able to adjust the pressures w/o a real hassle. Now I run 60 in the rears, 50 front and just bring the rear back up to 80 when I tow heavy. Rides MUCH better with 60 in the rear.

Everyone says the Bilstien 5100s are the shiz for these trucks. I've had Monroes on mine since ~80k miles when the factory rears went out. They're ok but keep hearing about the Bilstiens. Actually, just installed a set of them on my brother's 2003 duramax earlier today.

Greg,
You will love the truck.
