uploaded on 1/6/12 by RORlover563 (view files by author)
made for RoR 0.38
This is a mod to box5's goose neck. I made it shorter and made it have two axles. The mod was simply to make it look better when hauling stuff around. In my opinion the normal one is a little large.
Original trailer is box5s
Mod by me
And i know the mod isn't perfect. May over write the old one.

    *BUG FIX* LATEST UPDATE
    I'd like to say I've fixed the "Big Tex Goseneck.load"
    *ever sense .38's "Pinguinville" came out there have been various conflicts with the map's and it's own materials & meshes, merely the extent to which I altered the trailer is merely changing the mesh names to void such conflicts*
    *-all credit belongs to the original authors!!! I only modified material names!!
    "Fixed" list:
    *wheels
    *spawning errors on Pinguinville & Minima
    *wheel-face bug
    *suspension is on the wheels,where it should be, not on the ramps
    *the jacks raise and lower a little funny, but they work
    *also added two axel version with (slightly) less moving when parked, and backing-up bug is fixed

    the sliding-around-while-parked bug is still unsolved...if you have suggestions (or soulutions ^.^) to fix it plz let me know(PM me)

    if any other problems protists feel free to pm, but remember i just fixed some bugs, skinning and stuff is tangycrose 's domain
    All credit is held by:

    Selfsteering Trailer with Dolly

    How to use:

    Pull the trailer next to the load so the rear part is at the right place.
    Disconnect the rear part with F11 and pull the front part to the front attachment point.
    Use a crane to put the load on, the wood load also has invisible legs so it can be loaded without crane, use F9/10.
    The steering strength can be adjusted with F5/6 to fit to the length of the load.
    The rear part has manual steering for special situations: F7/8, don't use when the steering is already at maximum angle!

    The legs fold in automatically if you pull them up with F1, hold F2 until they fully fold out.

    The load will attach on the trailer automatically once it is close enough to the right position.
    To unload push F12, but attach it to a crane first and put enough tension until the trailer almost lifts off!

    Thanks to Lifter for the hookgroups and triggers and for support with this project!
    Thanks to fidoj for his roof part load!

    Please do not modify this without my permission,
    skins can be added using the skin file system:
    skins-working
    If this system is used properly then no need for my permission for skins.

    Talk about it here:
    Selfsteering-Trailer-and-Dolly

    You need a RoR version with working hookgroups and triggers to use this, 0.38.40 and up!

      This is a mobile home or mobile office depends on how you use it. You can pull it to your location and pull the tires into the body and it will be on the ground like a house. It is a decent amount of weight 22046.23lbs. It is fun to pull around comments are greatly welcomed. This is a 10x40 trailer its not a CAMPER.

      made by me


      Update 1. made the tongue longer fixed the tires problems added more weight

          This is a Krone Box Liner container chassis.
          It can carry 20' or 40' containers, compatible containers are in this pack:
          http://www.rigsofrods.com/repository/view/4251

          It can load 1x 40', 45' or 48' are also possible, but that may result in too much front and rear overhang and then the container might hit the tractor unit.
          The other possibilities are 2x 20', 1x 20' in the middle or at the end with retracted chassis back.

          You can extend and retract the rear end to fit different containers on, and it is possible to adapt the suspension to different heights and loads,
          the command keys show up in the ingame preview.

          There is also a version with two containers fixed to the trailer for people who don't bother loading or unloading it.

          If you want to reskin it please use the GUID system and skinzip files, then you can upload your skins to the repo.
          Don't modify anything else or use parts of it on other models without my permission please.

          The truck is not included, but you can get it here:
          http://www.rigsofrods.com/repository/view/3902

          The map is not publicly released yet.
