That 680 is way heavy, maybe you have a frozen front torsion axle not taking up its load fully?

Factory specs listed in a PDF floating around here:

1970 OVERLANDER DELUXE LY 27 TWIN: 4515 450 19
1970 OVERLANDER DELUXE LY 27 DOUBLE: 4565 460 19
1970 OVERLANDER INTERNATIONAL LY 27 TWIN: 4525 455 19
1970 OVERLANDER INTERNATIONAL LY 27 DOUBLE: 4575 465 19
(Figures: Dry Weight, Hitch Weight, Ball height)

This trailer does need axles, but the axles do move *some*. But that could be affecting the tongue weight.

I had seen those factory specs you quoted. I hope it is closer to that weight.

I weighed the tongue using a bathroom scale (using a bar to divide the weight in half because the scale wouldn't read high enough). When I got 680, I thought I must not have been doing it right. But then saw "680# HW" (for hitch weight?) penciled into the owners manual.

I am supposed to pick up the corner weight scales tomorrow night, so hope to be able to get some accurate weights this weekend.

Plus my weight distributing hitch arrived today, so can play around to see how it affects the trailer axle and tow vehicle axle weights as well.

The other things penciled into the front of my owners manual seem to be for other trailers - it has:
28 - 6720 unloaded
8200 GVW
25 - 6000 unloaded
7300 GVW
Mine is a 27 foot, and these are nowhere close to the factory weight estimate, so I don't think they are for my trailer. My trailer has dual 2800 pound axles, so the max gross trailer weight should be 5600.

Also, car wash soap and an extension pole with microfiber "sponge" arrived from Griott's Garage today (recommended on this forum). I got to do a *little* washing before it got dark. Still needs more washing. I don't know if you could tell in the pics, but this thing is DIRTY on the outside. I'm glad I searched this forum to see that I didn't want to pressure wash this camper - I was about to do it, and then thought I should search first.

Picked up the race car scales last night, and found time to get an official tongue weight tonite. 711 pounds!!! So I was fairly accurate (or lucky ) with the bathroom scale method I used before, when I measured 680.

I made sure to zero out the scale after the bottle jack was on it, so the weight of that jack wouldn't be included. I also used a level to make sure the trailer was level. And it was on a level concrete pad.

So I am far from the factory tongue weight estimate of 450 pounds. What could account for that? Is it the dual 40 pound propane tanks? Looking online, it looks like they are 30 (empty) - 70 (full) pounds each, so that would be 60-140 pounds added right to the tongue. My interior is original, nothing stored inside, and the fresh water tank is empty. I do have a ThermX heater, and a later-model fridge, so that could be some of it too. I guess every little bit in front of the axles adds up. The weight distribution brackets are on the tongue, but not the bars. I also have the battery removed from the rear compartment - it would remove some tongue weight if I put it back in there. I have seen others on this forum mentioning 800+ pound loaded tongue weights for similar trailers, so maybe it's not uncommon to be that heavy?

Will spend some time with the scales this weekend to get axle weights, total trailer weight, etc.

Sorry that we won't be able to make it to Alumilina tomorrow. Too much left to do on the trailer, and had a family commitment pop up in the evening. I hope you all are having a great time!

Oh. Great. Now I got another itch I can't scratch. Thank you for your reporting, with a full water tank my little 1973 27' 4500-pound trailer may have an 800-plus pound hitch weight and I am not happy with that.

Do you have the ability to lift the trailer at the mid-point of the axle mounting plates until the tires clear the ground, level the frame and retest?
