Hi, We are doing a road trip and Seattle is one of our destination stops. We are travel with a RV & I wanted to know if commuting to Space Needle via RV is feasible and will we be able to find parking for an RV?

Not feasible, difficult to find car parking! Suggest parking outside of area and Uber to the needle. And a note the needle is being renovated! I would call ahead.

Very hard with an RV

I suggest you take the ferry across and park at Brisbane Island. Great beach, you can park at the casino I imagine. The frrry is a great ride, and it docks a few blocks away from the needle.

When I went there a couple years ago I was in an big diesel with a long box an it was still hard to get around

There are several parking garages nearby, but they are pretty low clearance from what I saw. I would recommend searching for a garage that can specifically accommodate for your vehicle.
