The 2008 and 2012 are different chassis the 2014 is on a 24000lbs chassis and has 22.5 inch wheels, not sure on the 2008. We have owned our 2012 378XL since new, and are very pleased with the ride, the power that the V10 has to offer and we tow our 2012 Chevy Cruze and average 7.5mpg and without tow we get 8mpg. FR has been excellent in the minor issues we have had and they hold a rally in Aug and anyone that goes can get items fixed without charge. This year will be are first yr going and are looking forward to it. Also the web site
/www.forestriverforums.com/forums/ has a great deal of knowledge and will help if any issues arise. You can go and post questions and receive their input on the rig you are looking to buy. Again we love our FR GeorgeTown.
