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.

I drew up a similar version to yours, but I have been experimenting on different galley doors. Finding one that is both weight and cost effective has been the burden.
Swing open, can be heavy but stays open, until its windy.
Lift up, can be heavy, but acts as an awning for when your'e cooking.

and the latest one...I have been mulling over....Have you ever seen the aluminum rollup security shutter at the pharmacies.....(kinda like the roll top desks....) Yeah....I'm toying with this idea too....its trying to figure out the weight...every time I call the dealer, I get the "you're gonna do WHAT with this?"

Plan, Plan, Plan, Plan, Plan.....and plan some more.

I think I read somewhere that you should shoot for a 60%/40% weight to give you 10 to 15 % on the trailer hitch. I feel that your 60 should be measured from the start of the front wall of your trailer, not the trailer ball. The propane tank and box will give only a little % of the weight. It really depends on the amenities that you add inside and where you place them. For instance, air conditioners weigh anywhere from 60 to 100 pounds. Adding a tailgate mounted refrigerator will subtract from tongue weight, etc.

You should tell him sometime what some of us do with foam, canvas, and glue!

I am doing this exact thing with my pop up frame. However, the wife is insistent that we put a bathroom in it for a small Theford potty; it would be 24"x32" opposite of the entrance door. I'm also using an Ikea futon frame to make the full size bed into a bench seat that can slide to the back wall and give space for a fold up table along the bathroom wall. For the galley, I'm going to have a lower portion with swing out doors and a swing up hatch above, similar to the Colorado Teardrop's Mount Massive edition. https://youtu.be/TrrsCPVvvQY I love the hinged tables on the swing out doors.

Haven't seen that before
