And, the weight of the metal/wood in the trailer body is also in front of the axle, so you can put a lot back there before its a problem. The excel link works, I just tested it ( it downloads a zip file that needs to be unzipped). Its slow, but it works.

Ok I see. I'll need to do the math. I'd rather have the kitchen at the back so you're bringing back some hope. I thought it would not be possible.

This is the 2nd version of the design. I'm building the 3rd version of the design right now, so this design is outdated.
And what you're pointing is an open drawer, not the door. You should try to see it in 3D with Google Sketchup, I posted the skp file.

Basically you have 200lbs of tongue weight in this model, and any camping gear in front of the axle actually adds more weight. 200lbs is a lot for a trailer this small.
If you send me new numbers I can plug them in A=? etc.

Thanks dude. much appreciated. I dont have the real numbers here right now as I still don't know the weight of my drawers (and drawer slides are heavy!).
But you guesses it good. I can't have more than 100 lbs weight on my hitch (10% of 1000 lbs) so for sure I'll have to figure out how to balance all that sh** correctly.
I'll try to estimate this more precisely and run the numbers. I'll send them to you to review if you want.
I have questions :
- what is X ? LCG ?
- are W1 and W2 the weight applies for everything FROM THE AXLE or just at the end of the trailer ?
- is it true that the axle should be at least from 3/4 of the total length from the hitch ?
Some numbers I can give you :
* frame weight : 110 lbs + a 1/4 inch plywood sheet (48 * 72)
* axle + wheels : 75+20 lbs
* fridge 35 lbs
* water pump 10 lbs
* gas stove ~ 15 lbs
* batteries + boxes 108 lbs
* solar panel " 15 lbs (will be at the front of my current design, above the cargo space)
* charge controller + inverter : 15 lbs
* I will weight all my gear ASAP and estimate the weight of drawers (including slides).
* oh ! and I shouldn't forget about the spare tire (~10 lbs). I can install it either at the front if the cargo is at the front or at the back if the cargo is at the back
MERCI MONSIEUR !
