Planning a trip out west in June. Will go through Vegas then Death Valley and up through CA stopping near Sequoia NP and Yosemite NP. Next to San Francisco and up CA and OR coast to Columbia River. Do I need to make Reservations? If yes, how far in advance? Driving a 40’ MH pulling a toad.

You really need to think about Death Valley in June HOT HOT 110-115 deg. IMHO, I would reconsider Death Valley for another time during the winter or very early spring. Same with Vegas as far as heat, but if you enjoy the Casinos & gambling, shows and food you can deal with heat in air conditioned Casinos. It is not a real kid friendly destination. From Vegas I would take 1-15 to Hwy. 58 over to Bakersfield, then head up to Yosemite and Sequoia. From Sequoia head west over to Vallejo then take Hwy. 37 over to Hwy 101 then pick an rv park in Novato, Petaluma or Santa Rosa. Then you can drive over the Golden Gate Bridge to SF to do your sight seeing. Driving a trailer into San Francisco would be a night mare, IMHO and yes I did it once but never again. From 101 just head north all the way up the coast of calif. and Oregon.
You will be hitting the peak RV season in Calif. and Oregon.
MAKE YOUR RESERVTIONS TODAY for your whole trip. Reservations can always be changed or cancelled, just check the cancellation policy of each RV park. People make reservations in Oregon as much as a year in advance. Can you do this trip with out Reservations? Yes and some folks like to wing it but you can set yourself up for potential frustration and anxiety.
