Well at least you have a "man" size rig there to enjoy.
Having owned a 4wd Sportsmobile and having seen your rig in person a couple of times now I wouldn't worry too much about the length. You won't be doing any super technical trails and a 45 point turnaround is just part of the fun we have
I will say that the best thing I had on my rig was cameras on the front bumper that let me see right where I went, cameras on the rear (I would place yours on the roof) and even under the rig to see where the tires were.
This all fed through a usb adapter into my Acer little laptop that I used for nav. You could also feed it to a in dash stereo.
Total Vision down in Tucson did my setup on 2 rigs and they were great.
The cameras are cheaper now and worth doing to let you see all around & under a big rig like yours.
Looking forward to getting out in the dirt this spring when the wildflowers are blooming....I bet we could find some great mild trails for your "super EB"
