I have a 4x4 F-450 that I want to convert to single rear wheel, but still need a large load capacity...any suggestions?

Sounds like you need "super singles" here is one example:

Thanks guys,

USA6x6 is an option, but wouldn't I be better off going with a 19.5" or 22.5" wheel. I think I'll have more options than using a 20"???

Ideal would be 22.5" wheel, with a 37"x12.50 tire

Also, do I keep the dually style bed or do I have to switch to a SRW bed?

A 20" wheel would give you 335/80R20 (40.7", 5100 lb) or 365/80R20 (43.1", 7100 lb).
With a 22.5 the only offroad treads are too big for a F450 - axle breakers - 13R22.5 (45"), 425/65R22.5 (45"), 445/65R22.5 (46").

For the F450 axles, particularly the front Dana 60, the 335/80R20 is the safe limit. I have thought about this a lot.

Do I keep the Dually stle bed or switch to a SRW bed?

20inch is not too bad of a size, tires are easy to come by, basically you are looking at the same size tires as a Unimog, like charlie said I would not go above 335/80R20 as they start to get very heavy the ford is going to start having axle problems as well as brake and unsprung weight problems.

There are lots of tires available, such as Conti MPT80,MPT81, Mich XL, ZXL, XM27, XM47 etc. Most tires in this size are only DOT legal to around 60mph, a couple of them 70mph, if you need to drive faster than that these may not be for you. Like I said above, with tires this heavy at 70mph your suspension better be ready for a beating, the same goes for driving on washboard.

Search USA 6x6 at Pirate.

Here at the risk of getting cuffed...I would hate to see you have issues.

I think Stazworks is doing some super singles like that and a double bead lock. I hear good things about them.
