Tunnels on WA Hwy 14, Columbia Gorge

Thanks for replies. We're staying at Bridge RV park, right next to the Hood River bridge. I'd be afraid to take the MH over that bridge---tight enough with our full size van. So only options to get to the park are tunnels from the west or a tunnel from the east. I've seen many big MH's in the park, all with roofs intact. So we should be OK...

We'll also try the stretch of old Hwy 30 in the toad---haven't done that yet & it sounds great!
