Welcome, Michael! You'll get some great suggestions here. Don't be shy about asking questions. The Navion was a good trainer unit for your bigger motorhome.
With a bigger rig, be mindful of tail swing. One of my neighbors bought a new 34' Class A, and promptly tore the back cap off by turning before clearing something hard. Gas stations can be especially challenging.
May the trails always twist in your favor
May the tales always end in good light
May you have more friends than one campfire can hold
