2020 Thor Sequence 20L — Should You Buy One?

Typical asking price: $75,000–$100,000. This is one of the more reliable vehicles in its class — here's what to watch for anyway.

Kestrel Take

A more affordable Class B on the Ram ProMaster chassis — the Sequence offers van-camper freedom with a gas engine (cheaper to service than a Sprinter diesel) at a friendlier price than the premium brands. Verify the chassis, house electrical/water systems, and for leaks. A well-kept Sequence is a sensible, usable entry into van life without Sprinter running costs; the electrical and water-intrusion checks matter most.
