when installing rear discs, yeah, you should replace the bearings anyway, but im talking if you wheel your rig and should break an axle. you would literally have to carry another axle with a rotor already on it and set up.
granted, you could just carry a complete axle with drum brake setup, but then you would have to bleed the brakes after changing the axle, and you would probably have some brake steer in the rear end with one disc and one drum

with the GM based kits, all you have to do is remove the caliper, pull the rotor off, undo 4 nuts and remove the axle shaft/bearing assembly. put in new axle shaft and bearing assembly, replace the rotor, bolt caliper back on.
with the bigrocks kit, you have to remove the caliper, undo 4 nuts to remove the caliper bracket, remove 4 nuts to remove axle shaft and bearing assembly, press off the bearing assembly, press out wheel studs to remove the rotor, put rotor on new axle shaft, press in the wheel studs, press on the bearing assembly, put in new axle shaft and bearing, replace 4 nuts to hold bearing in place, put on bracket, replace 4 nuts, bolt on caliper.
besides, a GM based brake setup can be done for much cheaper.

The big rocks kit basically mount the rotor to the inside of the axle and you have to pound the wheel studs through the rotor and the axle plate.
The GM rotor has to be machined (which is already done for the kit) to fit the outside inner flange then it can be slipped over the outside of the axle plate

People use the GM calipers because they have an integrated parking brake and they are cheap and readily available. If you went to Toyota front calipers on the rear you'd need an xfer mounted brake. If you wanted to keep an e-brake that is. If you are installing discs in the rear might as well go floater for all the other benefits that comme with that. In fact the benefits of the floater outweigh the benefits of rear discs. The rear drums are up to the task but the rear semi-floating axles aren't for serious abuse.
