Holy Rust Batman! What to do?

I bought it from a dealer in Ohio. They said the undercarriage had been coated with a rust inhibitor and was in good shape so I was expecting a newish looking underbelly. Seems like I'll have plenty of work to do this summer on it.

Wow! Do you pull a lot in the winter? Does Colorado use salt on the roads? That looks really excessive.

Oh yea, I think this is pretty common. Best you can do is scrape off the loose paint and then use a spray paint with a rust inhibitor, and spray away.

My Springdale came with rust. The first year I had it, I scraped for a couple weeks all over the frame. Then used Rust-o-lium (black), brush on type and spray, oil based, not water based, with the rust inhibitor. The second year, I could see the spots I missed. I lightly scraped them and sprayed again. Third year all the way through to the 8th year of ownership, never saw the rust pop through again, or have paint flaking. I repainted the tongue twice, and touched up the parts of the under-frame that could be seen where it wasn't covered.

I crawled around under that camper quite often, and never saw rust pop through again.

I need to do some minor touch-ups on my current camper now too. But yes, your experience is very common.

Looks like a 20 year old car that has been sitting in a field.. That is a lot of rust for sure. You will have to have that taken care of soon... RV is only 3 and rotting...
