So the distance from the front of the van to the bed is the same for LWB and SWB, with the LWB you have more room behind the seats then - correct?Just fitted a 150 slider in my LWB T5.1 and the fitting is the same regardless. The only issue i had was getting the massive spare wheel back in the cage again due to the reinforcement under the van and having to tap the arch down to get the sliding part to clear the arch.
