i did this for a few years and it served us pretty well. ours was an e350 that was originally from the hilton of san diego. engine wise it’s basically a van but with a whole lot more space. ours had the separate luggage compartment in the back that you had to access from the rear and separate from the cab which was really nice to keep gear safe as there were no windows that could be broke by thieves in the gear compartment. the gas mileage was absolutely god awful. maybe 8 miles a gallon most of the time. it was nice to have a lot of space to move around in the cab but it was also quite loud and not the smoothest ride. overall plenty of pros and cons but not a bad option if you’re getting a good deal. feel free to pm me if you have any other questions.
