MBE 902 is a MBE 900 series engine, all in the series are essentially the same with some differences in ratings (programming) and accessories. Motorhome engine models often have higher HP ratings, for a presumed lighter duty cycle.
If it were still available it would be my preference in the 7 liter turbo-diesel class, only one at that size built like larger diesels. Freightliner or Detroit Diesel shops for service and parts. Most Freightliner shops are Detroit shops anyway, same parent company for many years.
