A small 12V test light with ground wire, bulb and probe is a very useful tool because it's very visual and it puts a small load on the circuit.
A cheap HF voltmeter is adequate for most DC checking
For AC a better insulated voltmeter should be considered, and one that physically holds one probe in plastic tabs is better since only one hand is near the circuit - attach the negative lead first. But truthfully most RVers should not be probing AC except perhaps with a no contact tester.
The 3 light plug in tester is also a useful tool. Consider one that has a GFCI test button.
