A word of caution: even factory 4 wheel disc are not that great.
I agree. I wouldn't expect any braking improvement by converting the rear to discs. When I went from stock sized tires to 35s, the stock brakes became a big problem with emergency stops. I installed the vanco super 16" brakes on the front and black magic pads on the rear and the improvement was incredible. The price was well worth the added safety on the street. IMO, upgraded brakes should be considered a top priority, especially for a travel vehicle.
