what size tire? The Dana 30 can be built to handle a decent load and you can mate it to a 44 or Explorer 8.8 in the rear.
If you're prepared to take on a big project, my standard suggestion is to look into late 70s Ford 3/4 ton axles. The front axle will be a heavy duty 44 with a drivers side diff, and it will readily accept the MJ suspension brackets (get aftermarket though, it'll be much stronger than stock). you don't necessarily need the rear from the same truck though, as just about any 8 lug dana 60 from any truck will match up in width.
