There are no code limits on the number of receptacles per circuit in residential construction. Commercial uses 180VA per strap to determine the number of receptacles per circuit.
Code has always allowed 14 gauge provided it is properly protected. Many local code amendments do not allow it however. THHN is single wires used in conduit. Chicago and New York City require conduit, possibly a few others. Otherwise Non-metallic is allowed and is commonly used in RV's. Romex is a TM version of non-metallic, the TM being owned by Southwire of Carrollton, GA, who many years ago bought out Rome Wire and Cable of NY, and thus acquired the TM to Romex.
RV receptacles use wire punched into a slot and the metal crimped on the wire. Not a good connection. Functional for low draw items. A heater is better off with a quality commercial receptacle, back wire where the wire slides in and you tighten the screw to capture it with an internal pinch plate, is best, much easier and as secure or more so than wrapping around a screw. (no, I am NOT referring to the push in cheapie receptacles, which by code are limited to 14 gauge anyhow, NEVER use them) I have been thinking I might install a box and good receptacle (have lots of Hubbell commercial on hand) and use it for a heater. Heater I have is 800/1500 watt and I vowed to never use it on 1500 watt.
