KZ was founded over 40 years ago and until a year ago was still owned by the founder (one of the original Jayco employees). They had a great reputation for customer service but they are now part of Thor. One thing to look at in that year there could be an issue with the roof membrane causing water to wick in and rot the underlayment....I know from experience...but mine was repaired free of charge by KZ even out of warranty. This was an issue in several brands including Jayco. Check the front and back corners to see if its soft. Overall KZ made a great unit...not the fanciest but well built. As for being able to tow it....knowing the engine and trans would help in answering....but if a big block then I would say no problem
