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.
What we checked
Not checked against public records
Motorhomes are in NHTSA’s database and we intend to use it. We have not switched it on yet because recall notices name sub-brands and floorplans rather than the model we key on, and folding them in carelessly would put another coach’s recall on this page. What follows is our own write-up, and it has not been reconciled against an official record. Treat it as a starting point, not a verdict.
