need opinions

i am thinking more and more od joining into the 6 wheeled family wit my dodge, its a long bed now, but thinking of converting to a dually since i need to replace bed anyways and all i seem to find is dually beds, could i do a chevy dually rear axle and some how convert the front to a chevy spindle or would it be easier to jsut swap a dodge dually spindle and rear axle and be done? reason asking is for rims if i do it

Is it already an 8 lug truck?

its a 6 lug i think its only a 1/2 ton and after thinking bout it it wil lbe more work then jsut a spindle damn drining will do that to ya.lol
