Well like I said, I don't have a cool sketch artist and I haven't mastered Google sketch-up yet so this is about as good of a concept pic as I can offer for now....
I'll post up some pics tonight as we have gotten the basic frame done. We chose to go with 3" 5# C-channel for the outer frame and tongue along with 2" angle cross members. The side rails have the standard 12" height while the drop tailgate is still being designed as we are taking into consideration a spare tire mount location. We'll be working on the tongue design tonight. I'm going to try to utilize an adjustable receiver tube so that the trailer's wheel base can be adjusted to match either a 2dr or 4dr simply by pulling a pin and sliding the tube in or out.
Also still up for possibility is a move from leaf spring suspension to an independent arm suspension with airbags. This would also change the cross members from angle iron to 3"x2" tube. Being that the trailer will already be wired with a 7 wire harness, powering an onboard air compressor won't be a problem. This will also mean a 1gal air tank would be mounted and available for airing up tires. This feature will ultimately come down to cost, so we'll see.
The best feature of this trailer is you can later add the M416 style tub as a straight bolt on, though the tub will actually be slightly bigger than the original M416 both in width and depth, thus more cargo capacity. I'm still re designing the tub to accept even more future mods as well, including an experimental straight vertical lift lid ran off of 4 electric 400 lb actuators. The additional height should provide the ideal height for RTTs that utilize the lower dressing/shower rooms. However this is still a ways off and I'm trying not to get too far ahead of myself.
BTW, if I stay on this schedule then this trailer will be at the Savannah Poker Run and it might even have a nice little "For Sale" sign attached to it....and before you ask, I won't know for how much until I'm finished as I will sell it at my cost...Not looking to PROFIT from this one!
