I'll take a rough stab at your weights. Remember, I don't know where your weights came from so I am going to assume from a brochure. I also don't know what you plan to carry, so I'll just show you how I would estimate the weights. You can adjust as necessary. I assume the rear GAWR is 7,050 lbs, since that's the capacity of the 2 rear tires. The empty weight is probably about 3,000 lbs +/- a hundred or so lbs. Let's do the Redwood first:
Brochure pin wt. 2,650
weight of hitch and rails 200
weight of batteries/propane 150
assume trailer cargo of 1,200 804 I use 67% since most fivers storage toward the front
Est added to rear axle 3,804
Est empty rear axle 3,000
Est loaded rear axle 6,804 this is with nothing in the truck
Since you have about 250 lbs left on RAWR, this might be doable if you pack the trailer extremely light and keep the heavy items as far back to the rear as possible. Also, that would assume you really don't have much to put in the truck. If it's you, wife and a couple of larger kids, then I probably would not even try it.
Since the Redwood is really too heavy, the extra 400 lbs of pin weight on the Jayco is certainly a deal killer.
With your truck as is except for air bags, I think you still need to look a little lighter. Hope this helps.
