    Right - I might be aiming for a doka ex firetruck then, I will need the seating for 9 persons and the storage capacity of a TLF 16/25 (pump 1,600 l/min and 2,5 cubic-meters of water in the on-board tank). This will not serve as a camper-truck, but more of a commercial people and gear transporter in North Africa.
    So a 1019 AF or a 1222 AF is relevant options - I understand that the 1222 is a OM421 V6 11 liter engine (R6?) and the 1019 has a OM 401 and is a 10,5 l. V6. The OM421 V6 is turbocharged as far as my research revealed...? The production of the 1019 stopped in 1982, a MY 1981 would be cheaper due to it's 35 years of age.

    Looks like spare-parts are more easily obtained for a OM421...

    A small overview: http://agrodoctor.com.ua/en/article/engine/mercedes

    Any insights?

    I believe you to be right with the numbers, but the OM421 in my 1222 is naturally aspirated. It is 220hp, and seems to chunter along quite well. Been hauling fire wood and rocks today and was making use of the usable torque on some hills! By buying the 1222 you are getting a later vehicle, with quite a different V6. The early ones always sounded like they were misfiring. This one sounds quite good.. The later truck you can buy the better IMO. I was looking at a 6x6 V8 from the mid 80's and then stumbled across the 1222 I now own. Its a 1995, has the later cab, and dash, and parts as you say are still readily available.

    Both Aspect http://www.aspectwheels.co.uk and Starco http://www.starco.com can provide/fabricate custom wheels with the offset/width/stud pattern/etc. for most applications. PM me if you need the name of a factory/builder that will also provide TÜV documentation for your new wheels (at a cost, and you have to go to Germany with the truck...)

    Hi

    When Bill Caid changed his 1017 to super singles I believe the 20" rims were standard HD Unimog. http://www.billcaid.com/2010/1017ACa.../TripMain.html

    A good source of tyres? https://www.vrakking-tires.com/stock/12-20-inch

    Default Decision made for me!

    Well, I'd 99% decided that changing from 20" to 22.5"s is the way I'd go. That's now decided! Gumtree came up with the goods. 10 22.5" Alcoa Alloys for little more than steels! They can sit until I'm ready to fit new rubber but, should set it of nicely! image.jpg

    Bat-trade do the wheels and tyres too, and could probably advise.
    There really don't seem to be any problems doing it on such a heavy duty truck.

    Mine is probably bigger than yours.
    (isn't that what those long signatures are about?)
    I'm talking about my truck, what were you thinking? ;-)

    Thx - If I end up with a 1222 instead of a 1019 I will weight it down to 10 ton anyway, I wont need the extra payload of the 12XX. Everybody wants the 1222 so the prices are fairly higher, and a 35 years old girl will be cheaper on roadtax, only 25%.

    So any insights on whether to go for 20" or 22.5" wheels when converting to super-singles on a MB 1017AF, 1019AF or 1222AF. Performance, cost and availability?

    Thx

    The only singles that you are likely to find on the shelf at truck tyre places in Europe are 385/65 on 22.5 inch wheels, as these are commonly used on the steer axle of heavy trucks. I suspect that the same is true in the US, although I saw lots cement trucks with huge 22.5 tires (425 or 445 wide). I don't know if the load capacity of the 385s is enough for the back axle of your truck, you'd need to check.

    20 inch wheels are not a common size anymore outside of military and specialist trucks, and so getting tyres is likely to require ordering them in, wherever you are. They come in a better choice of off-road treads, and if you want tall rubber, there's not much bigger than the 16r20 XZLs.
