A lot of trailers and motorhomes are near their GVWR as manufactured. Back in the 90s some Fleetwood morohomes only had about 300-500# of cargo and passengers left before they reached their GVWR. That's why I bought a Southwind with aluminum wall and roof studs instead of a Bounder with steel. The Southwind still had about 200-300# left after passengers and load. The Bounder would have been at least 500# over and that's with empty tanks, except propane and fuel. My Jayco class C was even better, with over 800# left.

others do.

I believe the statement that was being questioned was that "most Jayco's at 3500gvwr and under are overloaded brand new on the lot"...., no one is questioning the fact that some of the smaller trailers have limited CCC's, and/or axle ratings.

It should be noted that the reference example (link) used in an earlier post where the OP in that thread had a CAT axle weight of 3,100lb on a 3,000lb axle rating (2012 model 165)...., it should be noted that he also mentioned that in a prior weigh his tongue weight was 600lbs. Thus (3,100 + 600) = 3,700lbs, so 200lbs over his 3,500 GVWR, which of course can influence axle weight.

well..sorry to tell ya but they are more than close. My X17A has a shipped weight of 3150lbs. 42 lbs in the HW..gets me to 3200. 20 lbs of fresh water for convenience... I am within 100lbs of my axles rating before I load one personal item...

Do I care? not even a little bit but my statements are for the OP since he thinks he isn't overloaded and he likely is

Bent springs

Shackle inversion usually happens when the suspension is drooping to its maximum point. This is when the shackle is in line with the arch of the main leaf of the spring pack. While at this point, if the tire hits something while moving forward, its possible, and probable, that the shackle will fold backwards instead of returning to its normal position when weight is put back on the wheel. The shackle folding back against the frame, shortens the eye to eye length of the spring, possibly bending it. Shackle inversion is usually pretty simple to remedy, a lever of some kind is used to pry the shackle away from the frame and past the point of max droop, and then the spring will do its job and spring back to where it should be. Be careful though, as the spring attempts to spring back, it has some stored energy that will be released pretty quick like, possibly taking your lever and throwing it into the woods. Shackle inversion can be avoided by installing stops on the frame to limit the shackles travel, or designing a stop into the shackle itself. Continued shackle inversion may signal a need for heavier spring. Check the trailer weight at a truck stop with scales or a material yard. Your TT more than likely has Dexter Axles. If it is a Dexter this can be checked by looking for the name Dexter Axle near the center of the axle on the rear side. Below the Dexter name you will see a 9 digit number ( lot number). Rub a piece a chalk over the number will help bring it out.
With this number go to dexteraxles.com and the customer contact area of the web site. Give them this number and ask them to provide you with the axle capacity and spring capacity ( spring and axle capacity can be different. Also ask them if there is a heavier spring available which will fit your axle.
Hope this helps.

This is an interesting discussion, but I am a little surprised that it is something to discuss. When I picked up my first trailer (a 1995 Jayco) I learned very quickly on my truck forum that RV manufacturers, as a general rule, equip the trailers so that the suspension is completely utilized. That trailer ran at 103% of axle and tire capacity after accounting for tongue weight. It seems this is a common situation regardless of manufacturer or price segment. I just was reading a thread about a Mobile Suites fifth wheel - I gather a very expensive, high-end trailer - and the axles and tires were utilized at slightly more than total capacity after accounting for pin weight. It appears to be the rule to me.

I upgraded the suspension on my new trailer for peace of mind - I viewed it as part of the cost of the trailer. Now my springs are the weakest leak in the suspension - they are rated for the trailer weight - but everything else runs at around 75% of capacity.

I don't know why RV manufacturers do this - there is little price difference in axles, wheels, tires, etc. They just seem to cut corners whenever possible. For example, they used two little flimsy hinges on the bed platform, which quickly broke - completely worthless. I put on a full-length piano hinge - no problems since. That couldn't have cost $2 or $3 more at the factory, but they seek to shave those dollars off. I guess the public wants to pay as little as possible, even if these things would only make a $500 difference in the price of a trailer. I find it annoying.

I believe Luv2 camp wanted to know the possible reason for shackle inversion.
He had already up graded his axles but not his springs!
Everyone seem to be telling him of their experiences, but not the root cause.

I don't see any mention of any upgrades to his axle in any post.


standard axle and standard springs

I assume he is saying he changed axles when he said;
"I have a 2012 jayco 154bh which i done a axle flip on 2 years ago"
If this is not the case my interpretation of " axle flip " is incorrect, but the root cause and the possible remedy lies in my explanation.
