Hi there MR. Action Moderator Dude - so you want to take this on

Here is all of what I have - directly from my super duper 1978 Argosy Owners Manual. Weights and Ratings for the 6.7 Minuet.


Factory Weight w/o options or variable weights 2725
Allow. Addtl Weight (Axle System) 1075
If you add Addt. Weight + Factory Weight it = 3800 GVRW

Also,
Factory Axle Weight 2446
Allow. Addtl Total Weight Incl. Persnl Cargo 824
If you add those together you =
Gross Axle Weight or GAWR 3270

and finally
Factory Tongue (hitch) Weight w/o options 300

I've also got a whole list next to the above which shows optional Equip. w/columns for Total Weight and Axle Weight and Tongue Weight side by side. Whooppeeee PS Single Axle

I prefer Action. (like Cher just a single name)

The math I highlited above from your post, was that in your owner's manual or did you just do this to arrive at a GVWR? (Which is likely accurate)

The factory weight is the dry weight of the trailer. Adding ...
propane
water
waste water
personal gear - food, beverages, clothing and other wanted items
The total designed max trailer weight towing is that number of 3800#'s

The axle weight rating of 3270 (or as Andy stated earlier 3300#'s) is what the axle designed needed. The other 500 #'s are in tongue weight, tires, wheels. Because the axle doesn't carry the tires and the wheels. Note 7 to 10% of the trailer weight is on the tongue or the tow vehicle via the tongue.


Making an assumption that you are not taking a survey and you would like to replace the axle for some reason. the replacement needs to follow -
The bare min axle rating you would need is 3300 #'s. However if you go higher say 10% higher, this would give you an extra margin of safety. It does not mean your trailer is now capable of towing any more weight. Also the theory of bigger is better does not continue. So if you go up 25% in weight rating would that be better? Not really. First it is a waste of cash. Second getting too big means the axle assemble may not fit the unit. Last is the ride provided may not be suitable for the trailer. IE too harsh of a ride.

Using that as a guide your axle weight rating choice should be between 3270 and 3600 pounds.

Hello again Action - I have been reading up a bit in the Argosy Manual under the page titled "Loading". In the past, we did not spend too much time considering all this because we put almost all personal items in the back of our TV. The old axle just tossed everything in the trailer too much. Now that we are planning the replacement of axle, I plan to put items to stay in trailer & so, will end up w/more weight and we may in the future need AC, plus trying to figure out about placement of spare mount/tire. Those are the main weight gain concerns.

This part of your post is where I guess I have lost it...

The bare min axle rating you would need is 3300 #'s. However if you go higher say 10% higher, this would give you an extra margin of safety. It does not mean your trailer is now capable of towing any more weight.

What is the extra margin of safety for?

I want to post some info I am getting from the Loading page, but need to digest first.

I'm pretty sure we will go w/3500# axle.

I do appreciate all the time and trouble you are taking to try to make this clear.

PS. The GVWR came directly from the manual, not my addition.

Based on the data you have given your trailer should not exceed 3800 pounds when fully loaded and ready to tow. Taking it to a scale is a great start. It gives you a point A to know what you are dealing with and how much or little you have to left.

Upgrading to a larger axle weight rating, still means your 30+ year old trailer has old used parts on it with 30 + year old design limits on it. The frame, flooring and body are all part of the structure of this type of trailer. The entire axle (shocks, brakes wheel bearings) if all replaced are is the vast majority of the load carrying capability of the trailer. However I am not an engineer and I have never played one on TV. What I do know is your trailer was designed for a total weight limit. It appears to be 3800 #'s. To exceed that means you are taking the design into waters the trailer was never meant to swim in.

Getting the 3500 # axle gives you a extra margin of longer durability, may be better weight control when towing. Or better performance in it's job of carrying the load. This may show up as less sway or less adverse towing quirks. However it isn't the only component of the trailer that supports weight.

So it is like that childs game of the heads popping up and you have a hammer to hit the heads popping up. The axle is one link in the chain of the weight carrying job.

Adding options - this will drive up the weight, however the other personal items may add more than you think. BTW recent designs of A/C units have made them lighter, shorter and quieter. A place you can shed weight is water. It is 8+ pounds a gallon. 15 gallons of water carried is like 125 pounds. Likely more than your A/C and spare tire and wheel would weigh together.

PS don't forget to have tires that are rated at 1900 (or 1880) pounds each and keep them inflated to max.

Axle GVWR for my 78 Argosy Minuet

Greetings Leigh!

When my axle was replaced on the Minuet, I went with the 10% upgrade in load handling capability. It did make a world of difference in the coach's ride quality -- it is rare that anything changes places greatly, particularly when I tow with the Cadillac. The one thing that I wish that I would have done is insisted on a greater down angle on the torsion arms -- I gained very little in clearance which was my greatest concern.

One thing that I have noted with my Minuet is that it likes to be towed with its water tank full or near full. Its location immediately behind the "A" frame places much of the additional weight on the tongue which IMHO helps the Minuet to be such a well-mannered single axle coach.

Good luck with your research!

Kevin
