Just turned 20K on my Travato (Promaster) and no serious issues on chassis. Be leery of dealers. After service dealer interview immediately after purchase, nearly a year later they dented a lower rocker on passenger side when lifting to rotate tires. Any attempted repair would exacerbate damage.
Brake squeal when nearly stopped and fuel tank replaced due to early kickback when filling only issues, so far.
Very happy with Promaster overall, especially the turning radius!
