We have also had 2 Honda eu2000i generators for over 20 years. Both still run fine but they run fine because of regular maintenance, like anything mechanical.
Your lucky because you have options today that we didn't 30-40 years ago. I bought the Honda's because at the time, Campgrounds around us were getting prickly about generator noise. It was money well spent IMHO. Never had a noise issue.
But today you can buy portable power stations that make zero noise. But they are expensive and so is the solar to charge them. Best bet is to get one with as many recharge options as possible. A/c, dc, solar, a/c + solar, etc. . Also, fast charging is now a thing. One brand name portable power station will recharge from zero % to 80% in just 45 minutes. Not only is that impressive, it can be important when you have limited time to recharge. Most Campgrounds around us limit you to 2 hrs in the morning and 2 in the evening and are VERY STRICT about it and yes, you get fined if you violate it.
I am still in the research stage myself and trying to educate myself on the most current options. I would like to be able to charge the power station from a/c, d/c, solar, a/c + solar, d/c + solar and while we are driving down the road.
The trouble is, if you do anything to the truck they want to void your warranty. I think a power station will be my choice for this truck.
