Yes, the system proposed by cewillis is one of the simplest, cheapest and most effective ways to get some decent charge into the camper battery from the engine alternator. The shorter and thicker the connecting leads, the better it will work.
If it could be combined with as much solar as can be fitted onto the roof, then depending on the charging characteristics of the alternator control system (and not all are equal when it comes to charging remote batteries) the engine will provide a decent contribution towards charging the camper batteries while driving and the solar can finish it off.
Use that multimeter (with the leads reversed - black to common) to check any starter battery with the engine not been running for an hour or so. Should read between 12V and 12.8V depending. Too much higher and the multimeter is suspect.
