If you look at the mods I did to our 13' Scamp
, I think you could do the same to your Trillium
still sells the hardware. I replaced our factory table top with a custom built two piece unit that was hinged. It was supported by drawer slides when extended. The small table version made it very easy to sit behind or next to, yet allowed one to extend the table to full length while seated. Click on our avatar and go to our albums to see all the pictures.
