Hi
I have a 2005 Toyota Hilux Invincible.
I can get 3 bikes on the back with a bit of trick tying up.
My scorpa, my oldest son's Sherco 125 with my youngest Beta 80 in the middle.
A couple of old sofa cushions in between bikes and lean the outer bikes into the middle and tie up.
Not ideal but it works!!!!
Newer Toyota Hilux's are physically bigger but can't speak of load length.
When i bought the toyota i tried the mitsubushi but the turning circle is rubbish, the toyota is holding its price well too.
Good luck
