I would park the 36' in South Lake Tahoe muni campground and use your toad to explore 89 on the west side of the lake. Its a spectacular drive, and you don't want to have to pass anything up because you are driving in a motorhome. 89 is closed to 40'+ motorhomes on the west side of the lake (tight curves). Travelling around the east side of the lake is just a touch less winding, still spectacular. Use hiway 267 to Truckee, then hiway 89 to Lassen. I think hiway 89 is the most beautiful drive in all of California (but I live here so I'm not impartial). Sierraville, RR museum in Portola, Quincy, Chester, the list goes on and on. Park the mh in Chester and see Lassen in the toad, the road is very steep! Bumpass hell is something to see, but I think the trail is closed until 2020 (check with the park). With all the snow this year, 89 thru Lassen might be closed until AFTER July 4th (again, check with the park).
