When they say diesels have trouble in "cold" weather, it's not 40 or 50, it's 5, 0, -5, -20, etc.
Also, no way, stop, don't think any more about this. If you really want a truck with a diesel, then buy a truck with a diesel. Swapping engines if you're a non-mechanic is madness, especially if the gas engine still works fine.
Actually you are a little off on the price. I looked into paying someone to do the Cummins swap on my Excursion , instead of myself doing it. Dropping the truck off their and having them do everything, including supplying the motor , using my transmission was around $12k-15k. Prices varied on which version of the Cummins you went with and how much power you wanted. Sure you will never recoup the cost but if you have the money to spend sometimes having something useful and unique is worth it.
I ended up not doing it at all since I don't tow that much anymore and the V10 isn't horrible.
In the Hot Rod power tour this year there was a 1969 (?) Suburban with a Dmax in it. It was really cool.
The cummins swap is more common therefore probably a lot cheaper. And that price is in your area. He may have to ship the truck to a guy who does the swap. It's simply not a financially beneficial swap. I see plenty of "projects" sitting unfinished on Craigslist with the " I have 35k invested on this so don't try to low all me" and in the pics it looks like a pile of parts. If OP has a plan and a complete donor vehicle he may do it for 15-20k. And it's still a old vehicle worth x dollars. If you got the money to dump in it and it's some sort of sentimental value ok otherwise it would be cheaper to buy one that has a diesel.

Without a doubt. And the 12 Valve Cummins has the least amount of electronics if any to deal with. And for someone to do this it's more for the uniqueness than anything.. you will NEVER recoup you money or time spent.
For me I decided not to do it just because I rarely use the truck and I can deal with the V10 lack of MPG and lack luster power. If I fell into $10k or so and just had to spend it on the truck I'd do this , until then no. And they don't make Cummins Excursions so the option to buy one isn't their, you couldn't give me a 6.0 and the ones with 7.3's you would think were gold plated for the prices they want.
OP, something to think about is if you want better economy from your truck, and you intend to keep it a long time, you might just swap out to "taller" ring and pinion sets front and rear axle. This is assuming your engine is in good condition. You will need to change the speedo gear in the transmission or add a ratio box to the cable to get the speedo reading right again, but that's all.
Keep in mind the transmission already has an overdrive so don't get carried away in putting in way taller gears. But if you have 4.11s, and went to 3.73s, you would get somewhat better MPG.
Payoff time for 2 ring and pinion swaps will be a long time, but the ring and pinions last long enough to make me think you would eventually get there.
Excursions so the option to buy one isn't their, you couldn't give me a 6.0 and the ones with 7.3's you would think were gold plated for the prices they want.
You're not kidding. I sold my wife's Excursion to a guy. I wasn't even selling it but the guy approached my wife at the gas station and offered to purchase it. She took the guys card and I called him a few weeks later. My wife wanted something different smaller non diesel. I bought it off my boss for 4k with a broken front axle. $700 later we had a running truck. I never drove it so it sat a lot at the shop yard. The guy offered me 15k cash. Wife didn't like the Excursion anyway. I thought it was a stupid high offer but I wasn't gonna turn him down.
My ford is a 99 diesel 7.3 and I have people constantly offer to buy it when they find out its not the 6.0. And I mean some stupid offers are thrown at me. I just don't need a new truck right now.

another option for same result is a 'Gear Vendor Overdrive (GV)'. Many 4x4's just add GV to RWD portion and run 4x4 only in "direct".
This option keeps your low range ratios for CRAWLING, which is tough in an Automatic 4x4, but very important DOWNHILL crawling
