2015 Thor Challenger with Ford V10

Thor product owner, 2006 Hurricane 31D. Excellent chassis and house built on it. No issues with engine noise but the interior engine cover, aka dog house, has been sound and heat insulated (prior owner who ever you are, thanks). I've owned my 2006 for four camping seasons and after 30,000+ miles and 150 nights in the coach it has not once needed professional service or forced us to change camping plans. It hasn't been 100% problem free but nothing I wasn't able to take care of in my driveway. I do recommend giving consideration toward a used coach at least two years old. Your initial costs will be much less in addition to the prior owners taking care of any post sale warranty problems. New is nice but sometimes not always better.

Concerning a tow vehicle, your best option is to use whatever is in the driveway even if that means going with a dolly, transmission pump or whatever. Spending a few thousand to make it road ready will be 10X less than renting or buying a vehicle that is four down towable. My tow vehicle is a 14 year old Honda Accord. Costs me maybe 1/2 gal per mile loss in fuel economy, no appreciable power loss and no bank note poking me every month.

Good luck with your search but take the time to educate yourself including the saving or costs concerning cutting ties with your current rig.
