Suggestions Update on Banner Frames for Box Trucks?

It's been a couple of years since I did a full coverage banner frame system for a box truck. Last I used was something from these guys: wide4mat.com; system worked well but they were flaky to deal with. (getting info, pricing, order information, shipping). A search of old threads mentioned Ackland (trade only) and epicworldwide.com (apparently not) and I was wondering if there are other good systems out there that serve trade-only. For a 26' box truck, primarily short run local delivery.
