I have owned a Rialta Motorhome and loved the size and layout. However, the VW powertrain is getting unreliable and parts are hard to find. I considered different powertrain swaps and then decided to just swap the whole front end. I cut off the VW and replaced it with a 2019 Ford Explorer Sport. It now has a 365 HP twin turbo vs the VW 140 HP and has all the conveniences of a modern SUV. I added an Onan 2800i inverter generator for quiet reliable power and replaced the 7000 BTU A/C with a 13,500 RECPRO A/C and heat pump. I removed all the LP and use a 120v dorm fridge with an inverter. I replaced the troublesome rear axle with a 7000 drop axle. It averages 18MPG.
