square back rough draft drawing

I have been playing around with a design that will work on my old pop-up trailer and would allow 3-4 people to sleep. I am a little concerned about this being rear heavy. I plan to put my water holding tank, propane and batteries in the front but not sure if that will be enough. Any thoughts?

At a glance the proportions look to have the wheels a bit further forward than most teardrops, so I see why you ask.
If you put all those heavy items at the very front of the cabin it will likely be OK.

You might be wise to have a plan B in mind if you end up too light on the hitch ball, like moving the battery out into a hitch box, so you don't need to move the axle back on a finished trailer.
It's seriously important for safety have 10 to 15 % of total trailer weight on the ball.

I was hoping to have the door where I could climb in next to the mattress to help keep dirt off the bed but the more I think about it I am thinking about moving everything up and cutting the back of the trailer off to get my proportions more tongue heavy. I feel like that would be easier for me to do then move the axle. I have experienced towing a trailer that was loaded back heavy and man was that a scary experience.

Great site for helping locating your axle position. No need to guess.
