Older Camperized Van Wanted to Buy

Looking for an older camperized van in very good to excellent condition that has never been smoked in, rust-free and no leaks, with low kms and proof of regular mechanical maintenance. An older Chevy Astro, Chevy Express or Ram Promaster would be great, but I am open to other vehicles. AWD preferred. The best way to reach me is by email. Phone is a land line, so no texting. Please ask for Leslie
