Yes they have some very nice models available. I have purchased a few and tinkered with them to see how I could use them for O scale and to go with 1/43 scale trucks. Here are some mockups. With the BN Green I just printed the sides out to the size of a toy trailer and used double sided tape to attach the sides. They look sharp. I print on photo paper and give it a coat of clear coat after it is dry. It is shown next to a Lionel Trailer a lot more expensive but really nice.
And I have tried these on a set of AMT 1/43 wheels. I have tried to modify the print file to make it bigger for 1/43 scale as in the Coke trailers.
Also Walmart has some really cheap toy truck and trailers available for about $5 I have picked up some to use the basic frames and wheels etc. to put the printed body over.
They also by request produced a custom trailer railway scheme for our model rail club.
The 3 axle trailers shown I picked up are New Ray toy trailers 1/43 old ones that I was going to take the wheels off of to make 2 axle trailer wheels for the paper printed sides. They are a lot more $ then the Walmart cheap trucks but the wheels and frame parts are lot nicer.
