The other bulbs will rob power from the circuit, making the tail lights dim, perhaps blowing a fuse because it's more than the wiring from the RV is designed to handle. Maybe if you rewired the RV, beefing up the wiring, connections, and wiring to the toad you could run all the lights in the toad to handle the extra amperage, but it's generally a bad idea. In addition, the extra bulbs trying to light in the turn signal circuit might cause your RV's flasher to not blink properly.
