I chose to design a off road adventure trailer for my final project in my Technical Graphics class. This is something I would really like to actually build someday (soon maybe?).
This isn't just a basic mock up of what I want my trailer to look like. Most of everything on it is is modeled in great detail. I wanted to pay close attention to detail because solidworks will tell you the weight of your project depending on the materials you used. So with that in mind, the things that are steel, are actually steel, rubber parts are rubber, and the water tank actually has water in it... etc. I also modeled all of the hinges to actually work.
The battery, inverter, switches, power outlet, Air Pressure Gauge and the jockey leg are not designed by me. These aren't things I would fabricate myself, so I didn't model them myself.
Some basic pics:
With the lids open:
Battery and Power Inverter (I didn't design these, i pulled them off the web)
Control Panel and Control Panel Cover
Underside: You can see the two 2.5 gallon air tanks and the 30 gallon water tank.
Close up of the axle, spring and shocks
The trailer tongue moves in for off roading and out for highway travel.
My brother owns a aircraft maintenance business and is pretty good with fabric and upholstery. I will have him construct the tent.
Here is the deployment of the top and tent.
You can also see a sink and cutting table with two drawers.
Camping isn't this trailer's only function. You can take off the top and use it as a utility trailer.
With everything on it, the trailer weighs about 1600 lbs. Nothing my wrangler can't handle.
The tires were tough to make, but I modeled them after what my Jeep has: 35" BFGoodrich KM2s on 15" Mickey Thompson Classic Locks.
List of Features:
Trailer brakes (CA has a >1500lbs trailer brake law)
Extending trailer tongue
Swing away front trailer jockey leg
Optima yellow top battery
Solar Panel Battery charger array
900 Watt power inverter
2x 2.5 Gal Air tanks
30 gallon water tank
1.5" tube bumpers/rock guards
Removable top with fold out tent
Yakima rack (for snowboards, kayaks...).
TJ Fender flares.
How it will interface with my Jeep:
7 pin trailer harness
Air hose (to tie in to my OBA)
Military style pintle hitch
Heavy gauge 12volt line to help charge the battery.
I thought about making the trailer have a link suspension system that I could raise an lower with airbags or air shocks. But after sketching it up and some early models, I decided it was too complicated and expensive to be that useful. Maybe I can implement that with the current leaf spring set up. Trailer leaf springs for this type of weight aren't too long, nor do they have a lot of flex/travel. I would have to use longer vehicle springs, but then they'd probably end up being to stiff to use with an airbag.
Anyway, tell me what you guys think. Things I should add? change? delete?
