Newmar Ventana vs. Fleetwood Discovery LXE

I have owned my 2019 LXE 44H for 3 months now. I have driven it about 4K miles. Someone needs to explain to me why we need a side radiator? I live in Oregon where it is quite mountainous. I have pulled large grades while towing a Jeep Cherokee, ( the grapevine, Siskiyou summit, the cajon pass)and the temperature gauge barley moved. Plenty of power. Seems like the side radiator would takes out one of your storage bays? If the the coach works perfect why do I care? Every system on this thing is rock solid. Leveling is fast and accurate. Slide mechanisms are smooth and strong. I did have an issue with the windshield wiper that was fixed. Some shade adjustments. A couple latches that I thought could do better. All fixed under warranty. My last coach had major issues when new. Roof leak, leaking gray tank, warning buzzers for the air, etc. The LXE is a dream in comparison. If I had one complaint the paint job could be better. They could have sanded 2 or 3 more times between layers. Probably would have added 10K to the price of the coach. I like the paint job on the Newmar London Air. 600K plus coach. I test drove the Dutchstar and the Allegro Bus before making my decision. The LXE seemed put together better. So far I am not disappointed.
