I have a 1996 camper with a Coleman A/C. I bought the Supco SPP6E. My A/C has 2 round capacitors, one small and one large. The small one has 2 wires and the large has 3 wires. Which one do I replace? Both?

The small capacitor with wires going to the outside fan is the wrong capacitor. THe one with wires going to the compressor is the correct one. Typically the red and another color wire go to the compressor along with a black one. Don't connect to the black one. Use the red wire and yellow wires. You want those two connections.
You do NOT take out the factory capacitor, just add the second one to the compressor circuit to help shorten the time it spends in "Locked rotor" amperage, and shorten the time it takes to get up to full speed.
Make SURE that you put a screw into the existing capacitors tie down strap, or it can short to ground if the metal from the wires shorts our to the metal of the clamp.
If your compressor is not working right, then replace the small round capacitor with the red and yellow wires on it. It might be 25 MFD or 35 MFD, replace with the same size. Shape is less important, you probably can find one for about $10 that is oval, or round one for a couple bucks more.
