We are getting between 10 to 11 mpg.
Have to agree with Effy. This is our second Thor motor home. The last one we purchased when it was 12 months old, so someone else had done any first year warranty work if there were factory quality control issues. However, with regular maintenance, we had 12 virtually trouble free years with it.
This time we purchased new, and while we have had some things needing to be fixed, which can be aggravating, I cannot say enough good things about Thor's willingness to stand behind their product and warranty. For us, their customer service has been great! Realizing that virtually all new RV's have some factory quality control issues, and ours did too, the bottom line is that if we were to buy another motor home, we would still consider purchasing a Thor. They definitely had the best length, width, and floor plan for us this time!!
