We sat in one for awhile cooling off at the 2020 Tampa show. The sofa was comfy enough to sit on but I can't vouch for sleeping. If you have not already done so check out the Thor Sequence & Tellaro Owners & Wannabees page, which has lots of helpful commenters.
Thor was been a bit iffy on build quality - some are fine while others have an array of problems. The fixtures are definitely built for a low price point. But that front sofa/rear bath setup is a pretty uncommon layout so if you really like it there are not many alternatives. Embassy RV Traveler Sport (Transit) comes to mind, but I think they are build to order. But in this market Thor might be as well, so maybe Embassy is worth a call.
