Just switched over from a Cyclone 3800 to a new Cyclone 370C;
Regarding your questions about the master bedroom, As you know the Ti nose is stepped. At 6'1" I have plenty of headroom at the first level. At the second level the fit is tight for me but my 5'7" wife still stands upright after stepping up the short rise in the second step. As far as exiting the bed you need to do it from the side as exiting from the foot of the bed is quite a reach to the floor. It should go without saying that the small wardrobe slide is much smaller than a full size closet but it is still more than adequate for a couple, further you can place a couple of small storage/bins etc in the wardrobe underneath your cloths.
The master bath in the 370c is very spacious, large vanity, lots of storage and a really good size shower - it fits two.
As many have beat up the Ti design before about storage you just have to rethink the way you pack.
Here is a true comparison:
In our storm damaged 3800 that was replaced by our new 370c I carried the following in the basement:
Power hoses, Pail/wash/mop stuff/ Extension cords/Water hoses/2 large outdoor grass mats/Tool Box/Sewer hoses/Extra stuff for the dogs/chocks/levelling pads/5 large RV chairs/spare 20lb propane tank and our small Coleman BBQ..........................When the new 370c arrived I was able to fit EVERYTHING in from the above list except the chairs/BBQ and propane tank!
So really all things considered if you pack carefully you will do just fine.
As I have mentioned in my other posts, the towing dynamics of the 370c are just amazing. I put a full vote behind the benefits of the nose design from a hauling standpoint.
Hope this helps,
Adam
