Well here I go into Uncharted Territory.... as far as I know
As much as I have searched. I have not found a single camping application that truly fits my needs. First, I drive a 4-door Jeep Wrangler that can get me to campgrounds that 99.99% of the population couldn't imagine exist! If the trailer can't follow me to the campsite, what is the point? Second, many of those are in either rattlesnake and/or bobcat and bear territory that my Dog would think is just another chew toy until its too late!
Because my camping partner is currently a Rottweiler mix, I must consider her as much planning the design as a future Girlfriend. Depending on the amount of Fireball / Beer consumed, her ability to jump into a trailer depends on each log on the campfire. Even though her ability isn't changed, my ability to judge and assist can become quite impaired by the friends present! Imagine a Doggie Pee break on an elevated Trailer mounted Tent at 3 am? I can picture Dog and owner curled around a ladder at first light! Also the trail I am camped on may not be very wide, but I can pull 4' ahead to make more room behind the trailer so the door need to be at the back instead of a side entry.
In order to keep the CG and the profile low I have looked at the Folding Trailers available in the UK. (https://youtu.be/ZrjumcQ8EDU) In addition I was looking into the Independent Suspensions used in the Australian Outback for the chassis. The A-frame with airbags addresses many issues including ride height on/off road and corrects for campsites that are not level. (I always have an Air Compressor with me when I Camp) My goal is an off road, stand up, travel trailer with a cabin (6'5"+) with a high ground clearance (18 inch minimum) and a travel trailer(towed) height lower than my exiting spare tire (65 inch Max) on the Jeep with minimal setup!
I would appreciate any ideas you may have. I have spent some time thinking this though, but I'd rather address issues on pen and paper than Wood and Steel!
