100' of 30A RV cord has a 6V drop with a 30A draw. This is unlikely to be a issue for the OPs stated usage or most users unless the house voltage is low.

I would not recommend that anyone use a normal house plug for higher draw RV appliances. The typical 20A CB house plug circuit has MULTIPLE 15A PLUGS and some of those plugs may also be using power in addition to the RV. Using a dedicated 20A CB circuit and dedicated plug can be OK with closer management.
