I have had a full length ARB which was REALLY heavy, I think about 110 lbs or so and did not like it due to the weight and that it was terrible as far affecting gas milage.
I now have an INTI made in Venezuela which is about 80 or so lbs. It seems to not affect the milage as bad, until I put 4 Hella 4000 up there.
As far as low profile, the 1/2 AO rack would be the ticket, plus it's modular!
You asked how to get the full length rack home from the freight house... put it on the roof!!!!!!!!! Just my .02...
