Nice rig!  The Aluminum sided ones can really pack in the options with the amount of weight saving siding.
How does 33 footer tow?
		
		
	 
Pretty well, in my opinion.  As I mentioned, I personally would not tow anything heavier or longer.  I have a Curt WDH and I change the bump stops at the rear anytime I tow, which has helped with any "porpoising."  I have not yet scaled it, but I am confident I'm in the vicinity of proper weight distribution.  
We live in Central Florida, so the environment is pretty flat and wind is not a major factor.  Most trips are <200 miles and <3 hours total tow time, for perspective.  We keep the tow speed at about 55-60, depending on factors, but that's the most comfortable for me.  That is as much for the tow comfortability, as well as we fear blowing a trailer tire going any faster.  We experience the "truck suck" from passing semi's, but that is to be expected, and I have heard conflicting reports whether a 2500 would solve that issue anyway.
Of note, when I picked it up from the dealer, they setup the WDH, and it was not right.  Needed to redo it at another dealer, and actually had to talk them through what I wanted.  I found that odd, but unsurprising.  Just a tidbit for anybody looking to buy and pickup from a dealer.  
Also of importance, if going to an environment such as a show, remember your PAYLOAD capacity.  As so many have mentioned, that really is the limiting factor of these 1500's.  The salesmen I dealt with were not "pushy," but they would tote TOTAL TOW RATING as the selling factor.  Without the advice of 
@devildodge  and 
@IvoryHemi, as well as many others, I would not have known to value PAYLOAD as so important.  To me, that is the SAFETY LIMITING FACTOR.  But that's my opinion.
I am a "new" driver as far as towing trailers, so keep that in mind when reading through my perspective.  With that being said, I don't mind sharing my experiences for any other potential "newbies."  Purchasing this TT has been one of the best things I've done for my family.  I have 2 girls, both under 3 years old, and this specific trailer will function for years to come.  Yes, we probably could have gone smaller, but there would have been a near guaranteed upgrade at some point!
