> I don't yet have an outdoor power hook up at home, and had thought I could use a standard outlet for lights while parked
I have done this numerous times, the key is to not let your demand exceed what the house outlet can supply. If you are plugged into an outside outlet on a 15A circuit that only supplies other outside sockets that are not currently (ha!) in use, you can run more stuff than if you plug into an outside socket that is on your 10A bedroom circuit and already powering lights, computer, TV, and an occasional hairdryer. You sound like you have common sense so you have probably already thought of this and will be fine.
However, you might think about installing a dedicated RV outlet. When we built our house 6 years ago, one extra I added was a 50A outlet on a dedicated breaker where I typically park the MH. Very convenient and a plus when a coworker of my husband's came through and parked for the night, they were surprised that they could plug in.
