Both rigs are good rigs..the Newmar on the Freightliner chassis and the Cornerstone on the Spartan K3 Chassis which is a step up to their best one...You need to drive both rigs due to the different chassis....I can tell you that Entegra is a first class outfit when it comes to support and warranty. Newmar is also a first class outfit but warranty is only one year. Spartan chassis support is superb. you have two good winners picked out and so once you picked out your floor plan. DRIVE THEM...I can tell you with Entegra, they work with ANYONE to get you service you need. I have some good friends with an Entegra Aspire and one with a cornerstone ....both have had issues but Entegra stepped up and Spartan stepped up. Not that Newmar won't but they are on a Freightliner chassis....Note the Newmar has comfort drive which may be a difference as well. DRIVE then decide, you could not have picked 2 better winners.
