X 15 and K3 chassis

What are the differences between the X 15 and the Freight liner and Spartan chassis - filter location, type of side fan, any pros or cons with either application. Access to engine and or transmission issues.

We have a 18 London Aire on a Spartan chassis just like we had on our Essex and 1st LA. The service center has most most items located there, is better on Spartan then FL. Many FL have had the fan drive assembly come apart and destroy radiator and CAC. Spartan has Safe Haul for tow connection plus thicker frame rails. 5 year warranty for Spartan 3 years for FL. Spartan is only chassis for King Aire Newmar's top of the line coach. Spartan and Newmar have a long history of being the best out there.

Here is a link to the Spartan Chassis web page. The K3 605 is the third one down.
Spartan Class A RV Chassis - The Difference You Can Feel. If you click on London Aire, it will take you to the detailed spec page

If you go to this web page you can select the London Aire and download the Freightliner SL chassis spec sheet.

This web page will guide you through the Freightliner SL chassis features:

Spend some time studying both as this is a large investment. I'd recommend you consider touring the factory and looking at both chassis. I have no doubt which one I'd choose.
