The body lift is an option but you may run into some snags...
Lifting the body off the frame will stretch out your brake lines so you may have to get some longer ones, fuel filler tube extension may be needed, the shifter hole may need to be cut wider, radiator lowering brackets must be made, clutch line may need to be replaced with longer ones, steering shaft may need to be extended with spacers, plus whatever else may come at you during the process.
It is possible but requires a lot of adjusting to components that attach from frame to body etc.
The older B2000 Sundowners are coils in the front I think? If so, maybe a spring spacer can be made or a universal kit? Plus an axle flip to the rear? (this will get you around 5 or 6 inches in the rear though), or maybe extend the shackles on the rear leafs(I think with the shackle extend you will get half of what you lengthen it by, i.e. 1"extension on the shackle will give you .5" of lift). I have never worked on the Sundowners before but I would say try to explore that route first.
More research may need to be done.
Good luck, Keep us updated.
