Some good news -
I had a look at a Racro seat in a single cab Hibux at ARB (Traction4) today and it was much better than a stock seat - even in the cramped single cab.
I hear that the mounts can be adjusted so it would go back further, but I would loose some forward travel and hobitts might not be able to drive my truck.
I'm comfortable with that.
They cost the earth ($2000:o ), but it would still be cheaper than getting the Navara.
(That's a lot of cans of HTFU
)
I'm still going to have a long drive in one tomorrow for peace of mind, but the Triton is still #1.
