I can't really tell you how they compare to PS's, but I can tell you how my personal '91 F350 IDI dually with a service body compares to the gas engined service body trucks I regularly drive for a living and to more modern and smaller Japanese cars and trucks.
First off, these aren't really powerful engines, but they're adequate and they pull well. I never have any problem maintaining speeds between 55 and 70 on the freeway and they accelerate well enough that you're not going to slow down traffic. I used to have an International Traveller with a 3.0 Nissan Diesel in it and that was an utter slug in comparison. To me it compares to a full size with a straight six gas engine, but it tows better.
Maintenance wise, they don't really compare to a 2000 era Toyota. I've found lots of little things to fix on mine. On the bright side though, they are EASY to work on. They remind me of pre-emissions control gas engines in that regard. They're simple and you have lots of room to work.
As far as fuel economy goes, I just filled up and I went 178 miles on 13.7 gallons of diesel, making the mpg's almost exactly 13. That's mixed driving and I was hauling stuff on top and inside it for about 1/3 of that. probably 2/3 highway and 1/3 city. That's with a 7.3 IDI, 4x4, E40D, 4:10's, dually rear and a big service body. My best mileage results have been 16 mpg and the worst about 11.5 and I drive like a granny.
My usual work truck in comparison is a C3500 utility truck with a service body and a bucket lift on the back. I'm not sure the exact engine size in it, as it is a company rig, but it is a V-8. One thing I do know however is the kind of gas mileage it gets and that's between 6 and 7 mpg, as I figure it out every time I fill up and thank God for fleet gas cards. I don't recall ever seeing it get more than 7 mpg and it's a 2wd. In fairness however, I do a lot of city driving with it, probably 60%. My old work truck was a gasser F350 bucket truck and while it's been a few years I recall it getting similar mileage to my current company truck.
