Should be good. Most allisons will last If left stock. That year is known for overheating, it's a really cheap fix. All you need is an AFE mouth piece. Other than that it should be good.

Kind of..
The Aftermarket mouth piece will certain help, however depending on the weight you are pulling and the elevation/ grades you are planning a secondary cooling setup is the only way to fix the LLYs cooling issues if you are encountering them. There are multiple threads on here about it where I jump in to further detail and provide a link to the DIY thread for this fix in case you are interested OP. I'm not on my comp now so I don't have access to the link.

As far as tuning goes I would recommend an EFI live setup. Since you're planning on using he truck primarily for a tow rig I think a perfumed ECM w/ dsp2 switch would be fine for you, just having the tunes as an optimized stock and heavy tow tune / turbo brake. This would be way more cost effective than a canned tuner, keep your drivability same as stock, increase your mileage and keep your egts down. I would also recommend picking up a boost gauge and pyro gauge for the rig to monitor your stats while hauling.
Hope this helps a bit :thumb

Welcome to the forum! With all the miles you put on make sure that you keep up on trans and fuel filters. Get you a set of gauges to keep an eye on everything.

The only real issue with the 04.5-05 trucks are the potential overheating issues. For the money saved on the slightly older truck though, you could have retrofitted an aftermarket secondary cooler, an AFE/Kodiak/LBZ turbo inlet, down-pipe and exhaust and still come out ahead. It should be known that the aux. radiator on a '05 will control temps better than even the 06+ models, which still have been able to reach 240* ECT's with heavy hauling.

The only other issue that sometimes crops up is head gaskets... there's been all sorts of anecdote as to whether it's tunes or heat cycles that do it, but lots of people have gone 200,000 miles or more without having any issues with them. It's still cheaper to fix than the LB7's injector issues (01-04).

06 and early 07 are the best years to have, fewest problems, they have the 6 speed allison instead of 5 and they have the most power. 07.5 to present have the DPF and they are a pita. The LBZ's are very nice trucks!!

06-07 are the lbz series, which most regard as the best option you have as far as obs trucks go as they do not have the issues with the injectors that the lb7s did or the overheating when towing heavy in the lly series. In 07.5 the dpf was started in the new body style trucks with the LMM engine.

get an LBZ, reroute the PCV, and GO. in stock form it will do everything you want it to. since you are going to be in the truck that much and pull that much maybe spend a little extra to get an 06 or 07 classic. there's a guy on here with a small tune who hotshots, over 600,xxx miles on the truck. think he did injectors at 500,xxx and a cp3 just recently. STOCK trans

I would personally do
EFI tow tune- yes it's worth the money to get a pretuned ECM with a DSP2 with a quality tow tune
gauges- electronic (edge CS or CTS) or mechanical. EGT and boost a must
exhaust- 4" straight can be had ~240 with muff ~280
reroute the PCV- super easy. all you need are the breather fittings that can be bought on here and some heater hose and zip ties.

let us know what you end up in. you really are in the cat bird seat buying a used dually. they're generally harder to get rid of than a SRW

Dont get the LMM, you will regret going with the emissions controlled motor. LBZ is where its at!!
