Default Axle Placement Feedback

I'm in the process of putting together this lovely 40' 5th wheel trailer and just looking for some feedback on the axle placement before I nail them in.
Camper weighs 3,000lbs dry
Jeep weighs 5,000lbs
Tandem 7,000lbs axles on the trailer.
Tow rig is an '04 dually Silverado.
Any input is appreciated, thx, Jay.

Just checked it out and it looks like my axles are positioned pretty damn close to one of their similar sized trailers.
Their axles are about 73% to the rear in relation to overall length. Mine are about 71%.
It obviously really depends on the position of your load tho. I'm just wondering if I should move my axles back a bit more because of the heavier jeep in the rear compared to the 3,000lbs camper up front. I may be just over-thinking it tho.

It isn't always about total weight so much as leverage and vertical tongue load/king pin weight. Keep in mind you will probably add 200-500 lbs of water, plus clothes, bedding, food, cooking things, kids toys, and other random stuff. I seem to remember reading that weight should be split 60% in front of the axle center point and 40% behind. Akoz? Akozman? Built somthing very similar to this. He has a thread somewhere on here.

Ya I've def read thru his build thread, he did an amazing job. That camper is huge compared to this one tho, it's only 23'.
You can only do so much reading and calculating because it really doesn't mean anything until you run the trailer over the scales. Problem is the axles the axles usually have to be installed to do this lol. I'm just trying to get them as close as possible so I don't have to cut and relocate.
Both water holding tanks are at the front of the camper. I also left about 2' of storage space for gas cans, generator... So that 3,000lbs of camper weight will be closer to 4+, which should help balance the weight of the jeep.

Ya 1TFROT I saw pics of your setup when it was for sale. Very similar rig specs, I'm 115"WB @ 5,050lbs. My setup will just have about 10 more feet of camper.
Do you know any of your trailer axle weights or pin weight or axle position? Looks well balanced.
Nice new buggy BTW

I'm no expert, but with just a 3000lb camper I would move the axles back another 18-24". I really loved how my camper pulled and the tongue was kinda heavy. You could also weld on 2 sets of spring hangers so if you don't like it forward that much it would be easy to unbolt and move them back, just leave some extra wiring. I assumed 2000lbs of gear, probably should have gone with 3000lbs.

Sounds good guys thanks for the input. I don't have the room to move them back 18-24" due to interferences but I am going to slide them back about a foot I think. I may just weld all the spring hangers to a big piece of angle iron and then bolt the angle iron to thru the frame so that I can adjust if neccessary after weigh-in. Then weld it all solid once I'm happy.

Couple last ?'s:
-What are your clearances from ground to bottom of frame? I can set mine anywhere from 20-24", would like to keep it low but don't want to risk bottoming out all the time getting to camp.
-Where are you fastening the camper to the trailer? Thinking I want to take into consideration the flex of the trailer over the length of the camper. Don't want to bolt it down to death and risk damaging the camper.

we fastened mine right to the d-rings on the trailer using turnbuckles and stock camper locations. it also sat on a sub-frame so it couldn't move around.



most of these style campers are not meant to be 100% secured down. you'll rip it apart from the walls flexing and the floor not

Ya truck-bed campers are easy, they already have tie-down points. It's a different story with an actual camper.
I'm thinking I may just bolt it down in it's 2 current weight bearing locations; the spring hangers and the pin. This should give it some freedom to flex a bit if necessary.

Made some good progress over the weekend, it went from 4 sections to a rolling chassis.
I ended up scooting the axles back as far as I could, hopefully it's enough, it's looking like it'll work now that it's all together in one piece.
I also ended up bring the ride-height down about 5-6" to cut down on the wind factor as much as possible. It's sitting at about 19" from bottom of frame to ground.

I hope that sway is an optical illusion.
