I guess it really depends on what the factory dry weight of your unit is ?
It also depends on your comfort level with some of the numbers.
When we ordered our trailer, I expected it to come in at the manufacturer specifications of 3200 lbs and 500 lb cargo carrying capacity. When I picked up the unit the actual unit dry weight was 3450 lbs & Cargo Carrying Capacity just over 200 lbs. I actually took my unit to a scale and weighed in at over 3500 lbs with no personal cargo.
The tongue weight of the trailer is about 300 lbs so in the end the axles/hubs/rims & tires were bearing about 3200 lbs of weight with "no cargo" (ie: no dishes, no clothing, no gear, empty fridge, & empty cargo hold, empty holding tanks etc).
The GAWR (axle weight rating) for the torsion axle supplied by the factory is 3500 lbs. I think the hubs were rated at 1800 lbs each as were the rims & tires. I did not like the way the numbers added up for margin of safety on a "single" axle trailer. Maybe with a dual axle I would have been comfortable knowing that there was some redundancy in the system.
Just had visions of a scenario of the "tail" wagging the "dog" situation if something catastrophic happened on the highway. I am also carrying precious cargo of my family in the tow vehicle
Bouncing down some of the rough roads and highway did not seem like something I could do without wondering how much tolerance there was for the close tolerances. It may have been okay, I don,t know. In the end it was my fault for not doing a little more research on the GAWR prior to purchase. (I should have known to look closer at the GVWR of the trailer and that would have tipped me off that the axle/hubs/rims/tires were under rated).
I replaced the whole system with 6000 lb Dexter Torsion Axle, 2500 lbs hubs & Rims & Tires.
