Appears TV can be closer to trailer? Perhaps portion of front trailer face that is below TV roofline can be angled forward a bit to parallel (maybe not quite) TV rear, and "match" trailer rear style-wise?
Perhaps the entire roof could be lowered a skosh- do you need more than, oh, 6'8" of headroom at the peak?
I wonder if the boat-tailing angles top and sides could be steepend a bit more, especially towards the very rear. It would be a nice goal to have a trailing wake area that is less than or equal to that of the TV alone I'd think.
Be careful of weight and balance- you do NOT want tongue lift! Perhaps axle should go back a bit and/or length shortened?
Looks like a good start to me though!
