Accessory mounting system for a vehicle and method for using the same

An accessory mounting system for mounting an accessory on a vehicle, the accessory mounting system comprising:

• a stacking assembly comprising:
• a support structure adapted to be coupled to the vehicle, the support structure having a length extending along a longitudinal axis and comprising:
• a first support segment having a first fixture end and a a first interlocking section extending from the first fixture end;
• and
• a second support segment having a second fixture end and a second interlocking section extending from the second fixture end, the first and second interlocking sections being adapted to slidably engage one another to selectively define the length of the support structure and position the first fixture end opposite the second fixture end;
• a support segment latch adapted to selectively secure the first support segment and the second support segment together and block movement of the first support segment and of the second support segment along the longitudinal axis;
• a first mounting fixture connectable to the first fixture end;
• a second mounting fixture connectable to the second fixture end, the accessory being selectively connectable to the first and second mounting fixtures for connecting the accessory to the support structure, wherein adjusting the length of the support structure correspondingly adjusts the distance between the first and second mounting fixtures.
