Here's the link to the Harbor Freight website with the bed extender: http://www.harborfreight.com/truck-bed- ... 45830.html
It is $70.00 and you can usually get a 20% off coupon that will bring it down to $56.00. My Hobbie Dealer sells the same extender for around $150 but gave me the headsup and said Harbor Freight sells the same extender for a fraction of the price.
The extender can also be switched so that the longest pole is set up vertically. This will enable the rack to extend even with the roof rack on a SUV/car/truck with a camper shell. Very simple, solid, and effective way of transporting your PA!
You will be amazed how easy it is to load your PA into your bed for a mere $56.00...no need for a cradle or PVC. If it makes you feel better you can add PVC to your bed but my Hobbie dealer said there was no need for the PVC and I have never had a problem without it! I would be interested to hear from others if PVC is really needed...and will start another post!
