Peterbilt 389 with Ultra Sleeper




A 1:17 scale Peterbilt 389 model with an Ultra Sleeper in white with tan accents. Uses two IR receivers for remote control playability. PF functions 1 XL motor for drive, 1 servo for steering, 1 m-motor for remotely controlled switch operating the lights.

The chassis, hood, cab, etc, are very similar to my orange 389 daycab.

I use this truck to pull my matching white fuel tanker

    I've built 3 of your trucks over the last few years, all very nice.  I do have a problem with the 389 with sleeper model.  The frame sags between the sleeper and the cab.  Has anyone else had this problem?   I've also built the tanker trailer and black lowboy.  The Tri-axle servers as the prim mover for  Ingmar's  lowboy with the jeep and booster.  All of your designs are crowed pleasers when on public display.

    Great work!! I love the white/tan look. I have the chassis built. Smooth, solid construction. Fun to assemble. I need to order some white parts to complete the body. It'll be on my display shelf for a long time.

      Thanks.  I've got a tanker trailer that I built for it.  However, it's quite a fragile and heavy build.  It's available here

        It's the perfect compliment to the 389 and I'd love to build it but I'm not good with fragile builds unfortunately. By heavy you mean heavy as in weight correct? Just wanted to make sure I understood. If you ever come up with a non fragile trailer that compliments as well as the tanker I'll definitely be adding it.

          Maybe I should ask what part of the build is fragile. That may make a difference. Thanks!

            As for the trailer, well, if u mishandle it and accidentally put some pressure on one of the side walls of the tank and nudge one piece off the side, it would be a pain to take the entire side wall off to fix it.  So if you've got small kids around I would not advise having it around them other than up high on a shelf.  So far, I've been really careful carrying it from shelf to floor and haven't run into these kinds of problems.  But if you're only used to building technic-only models which are pretty robust, I would advise to build some sort of lowboy or flat bed trailer instead.

              That's not a problem. I can handle that. It's worth the more cautious handling necessary due to its looking so damn good with the tractor. Glad I asked.

              I'll b sending u a PM if that's OK. I want to make sure I understand the PF hookups on the 389.  That's my weakest area. I get confused ;)
