Update to thread....Added a second set of rod holders to the truck bed and an additional photo.
Added PVC caps to the back ends of the pipe and found another materials receipt not included in my original cost estimate. The total cost of materials, not including the 2x4's and dry wall screws was $50.00 or $25.00 per set of holders. Still seems reasonably affordable.
Materials List (for 2 sets of rod carriers as shown in the below photo):
1 - 8' 2x4 and 1 - 2' 2x4 (may need more or less depending on your truck. As show in photo: 4 - 20" pieces, 2 - 11" pieces, 2 - 4" pieces, and 4 - 2 1/4" pieces)
4 - 5' lengths of 2" Schedule 40 PVC
4 - 2" End Caps (optional)
4 - 1" x 6' Tube Insulation (goes inside PVC and gets cut down to fit)
4 - 2x4 Bar Clamps (holds frames to truck bed rails)
8 - "J" Hangers for 2" PVC
8 - #6 Machine Screws & Nuts (3" long, trimmed down after final tightening. Use one for each "J" hanger)
16 - Washers for #6 Machine Screws (two for each screw)
24 - 3" Drywall Screws (for attaching 2x4 frame pieces together)
6' of 3/8" Bungee or Shock Cord to hold rods & reels in
Can substitute Velcro Straps or any other thing you wish.
Hope this proves helpful and useful to others.
