You are not alone (and Thor isn't the only one with quality issues).
- Poor handling: The first thing any Motorhome owner should do is get an alignment
- broken windshield washer pump: Thor had a bad run of these (I had to replace mine), although I thought the run was only with the Axis/Vegas line. Perhaps there are more..
- cracked & faded dash: How long was your coach sitting on the dealers lot?
- bad coach batteries: Were they Harris batteries?
