Truck Camper with Built in Genset?

Many truck campers offer the generator as options . We ordered ours with the generator because we do a lot of boondocking. Ours is the Onan 2400 propane and runs everything in the camper if needed has the remote start from inside and an hour meter which is pretty standard. We also have two 30 lbs propane tanks . The generator is very handy for quick stops but it is noisy and does use a lot of propane . I added an onan resonator and it helped a little bit with the noise. We have found that The built in generator is good for using the microwave or if it is really hot using the ac to cool the camper down but for charging your batteries it’s propane use and noise make it hard to justify. What we now have is a 200 watt solar panel and 1000i Honda generator for maintaining the batteries and the built in basically gets used for the microwave or ac . We have a inverter so most every thing runs from our batteries.t I also have two 2000i Honda’s from our fifth wheel days but the 1000i does the charging job just fine and it’s lighter and smaller to carry . The built in is convenient but the solar and Honda are quiet and efficient and all three just about cover any situation we have come across
