Re your trip from Sacramento to Eugene ......Redding has a casino but I don't believe they allow overnight the one in Corning is great .. We stopped there often I know it's a little soon to stop ..... also if you drive a little longer to canyonville in Oregon the casino there 7 feathers has a 5star $$$$ RV park and overnight pull through parking area ( free) beside the casino. I have also used the Walmart in weed ca . The trip between Sacramento and Eugene struck me as more like 8 hours but it's been awhile and my trip was always Portland to SF
Something to add to your overnight stop options are casinos , most allow overnight
