Suspension Options

I am in the process of buying a new trailer and have not been able to find a good source of information and recommendations for a dual axle trailer suspension. Here and there, a manufacturer will mention that they have some type or brand of suspension but don't explain what that buys you. I have also see something about wide width axle spacing which supposedly provides "stability". Most of the time, they don't say anything. Is there a good source of information on the alternatives where I can look? Also love to hear any personal recommendations?

I plan to do some amount of driving on gravel roads and will expect some washboard road situations so would like to get a suspension that can help smooth things out a bit. My old Casita with a single axle trailing torsion bar suspension was pretty rough on cargo so hoping to do at least a bit better than that. I am looking at a trailer with overall length in the low to mid 20s.

  • Your referring to a tandem axle set up which your going to like much better than the single axle set up. Much much smoother ride.

    I've heard some folks with the wide axle spacing between the tires say they couldn't tell any difference vs their previous close axle spacing units. Keep digging and check out other TT websites. More heads are always better.

    IMO, many TT suspensions (leaf springs, axles, tires) are "at the edge" of their max weight loads. They are sized based on 13% weight on the trailer tongue (on the TV's hitch). Thus, not needing the full weight load numbers. Ya, good way to keep the lawyers away during its warranty time period. But, very risky when loaded heavy and/or across rough driving conditions. Thus, reason for many snapped leaf springs and/or axles out of alignment (which wears out tires much faster).

    For "average" paved road and normal speed gravel road driving, I think "wide track" (re: axle being 1-2" longer) has no great benefits either. IMO, its more of a marketing thing. Especially since most people "slow down" on rougher driving conditions. It's like having auto vehicle tires distance 1-2" wider. I cannot feel the difference. LOL!!!

    If into rougher road (but NOT off-road) driving conditions, I would simply buy a pre-owned TT and with money saved (from going 1-2 year pre-owned), upgrade its leaf spring packs to "next size up", upgrade its axles to "next size up", install after market shocks and install Dexter EZ-Flex yokes. re: - click here -

    And being pre-owned (past its usual 1 year warranty time period), install other MODS you want as well. For example, brighter rear lighting, 12V Chassis battery switch, etc, etc. Money saved means more remaining dollars for "better than factory" upgrades - like suspension upgrades.

    Hope this helps...
  • Look at Komfort and Arctic Fox, there may be others. Good luck finding a quality unit.

    Honestly I would focus more on getting higher rated wheels and tires. Most oem are pretty marginal.


    yes.
  • Komfort has shock absorbers .
    Also reserve capacity in loading weight .
    Made in Milwaukie Oregon and made for rougher roads .
    6 inch tall steel frame , welded aluminum structure , extra ground clearance , and so forth .

  • Some trailers come with shock absorbers. Northwood Mfg. (Artic Fox, Nash?) and Outdoors RV Mfg. for sure. Also, the high end models of Outdoors RV and others add rubber cushion based links to the equalizers between the axles.
