excellent pics all.
my SD just clears my garage door by about 3" so a topper
thats taller than my roof would be to tall. so looks like a same as roof height topper.
Also, looking online at new/used units their seems to be some contention about
the fitting of a '08 vs the pre 08's like will a '07 fit on a '08 but from what I can tell
unless its for an '08 then its a try before your buy scenario
Thanks all thus far.
