If the seat and awing are your only complaints, then consider yourself lucky.
Be certain to do a complete PDI (Pre Delivery Inspection) BEFORE you hand over your $ or sign a finance contract. All RV's will have issues but what I have read in here, it seems Thor does have their fair share of issues.
Be sure to cycle the slides in and out several times to make certain they have corrected the issues with some of their slides. Do a search using "Thor" and you can read about these issues first hand.
Granted the complaints are relatively few considering their overall market share, but to be on the safe side, inspect and try everything before taking delivery.
