Thanks - we are very please so far.
We kept on cycling back to the AF990 because of the large dinette, high ceiling and overall "homey" feel. We also like the folks at TC Warehouse and feel good about having a solid dealership relatively close.
Found some SS 5/16 shackle padlocks for the fastguns and I'll swop the tiedown clips for some higher strength bolts to keep folks honest and avoid the bend problem that was mentioned.
I don't expect any problems but it's easy peace of mind.
Got some light weight locks for the gas bottles too.
