Thanks to all...Here's an update...And I would REALLY appreciate additional feedback. I visited one manufacturer and a couple of sales lots, did a lot of measuring, some photos, etc, and here is my current thinking. I would appreciate ideas, feedback, and any suggestions as to sources who I could work with to think out/engineer, and then build this for me. I know that I'm going to spend some $$$, but I want quality and versatility without just throwing money away! Here's my current thinking, along with a bit of the rationale behind it...
A. Heavy duty, low profile, gooseneck dump with two 7k, braked axles.
B. Flat, 18 foot deck instead of box.
C. Rub rail with plenty of stake pockets and at least 8 "D" rings for binders.
D. HD lift mechanism, jacks, loading ramps, and tool/chain box(es).
FEEDBACK PLEASE???
A. Sources for building it?
B. Type of lift mechanism?
C. Type of deck and material?
D. Other ideas or "watch outs"?
Here's my current thinking...
A. The flat deck will be much easier to load, arrange, and tie down.
B. With a 7'x18' deck size, a set of low and manageable stake sides will allow me to carry as great a weight of material as I want to manage.
C. The 18' deck length (vs. my original thought of 16'...thanks for earlier input!!!) will allow a bit of leeway for load balancing (I do have a tongue weight gauge). With the gooseneck, the rig will still be reasonably maneuverable, and this is probably a good compromise.
THANKS FOR ANY IDEAS AND INPUT!!!
