Sundial/EZ Campers/Riviera/ASI
Again relying on Hedges, the Sundial tents have frills along the edges of their flat-roofed awnings and use a shower-ring design for attaching the side panels. Stripe widths and styles varied. Hodges says there's even a two-sided Sundial tent for double-door busses (cf. below).
At long last I can show you a few photos, thanks to helpful readers. First, in April 1998, Scott Fraser posted a pic of a neighbor's tent that was for sale (at $350, and reportedly only set up twice in its life). That's what you see in the first two pictures here (Scott has offered to take more photos & pass them along).
Meanwhile I got a reply from the seller (Steve) -- all he could add was that "[the PO] only pulled it out of it's bag once & I the same. Poles are out of
galv. steel. Brackets ( 2 ) mount to top of bus & sides hang from shower hooks."
Immediately, alert type2 list readers Todd S. & Carrie W. and Rick confirmed that this was a Sundial. The third image is drawn from the late Josh Rodgers' very good Sundial Page, which I believe has been replicated somewhere but I've misplaced the URL.
All is not clear, though. (Compare the Privy Tent-like legs on the photo from Josh's site with the blue tent above!) Charles \"Luke\" Lukey wrote to say "The tent that has been called "Sundial to a T" is probably a tent made by the Beckel Canvas Company in Portland, OR. It's an exact match to the tents seen in the Northwest on Riviera campers. I've got one just like it (in green & white) for my '67 Riviera. The Beckel Canvas Company is still in business in Portland. They specialize in heavy pack tents for hunters. Great people - they sent me (free) a few small latches for my tent." Luke is looking for more info to add to his Riviera article.
The plot thickens: Jack Maynard submits this photo of "Dustin Mitsch, with a tent I sold him which matches perfectly his 66 Riviera camper. It is a Riviera tent, evident by the fringes, and hooks that allow it to be set up several different ways as far as the doorway. It has no floor, and is supported at the bus by a strip of metal that a bead in the end of the canvas rides into, and three poles out from the bus in the roof, and two down to the ground, fitting with normal american style plastic spike-ends into holes in the canvas and the other poles."
Jack added later: "I have seen what folks were calling a sundial tent and it had more of a scalloped overhang with very short fringe. Who knows who made the tent I call a riviera tent, but I know I have seen several on riv splitties that were obviously part of the original package sold at riv motors. Colors matched too well, and tent rail attached exactly like other examples of rivs. I confess I have much less experience with sundial, and for all I know sundial got their tents from the same place riviera did. I did see an ez camper here in corvallis with a similar tent, but it looked like it had been added to the bus much later than its original conversion."
So did Beckel make tents for Sundial and Riviera (and others?)? From some additional shots taken at the 1998 Bulli Brigade, you can see that this Sundial (?) tent has the classic shower-curtain sides, scalloped/fringed edge, and roof brackets:
Here are a couple of pics of Sundial roof brackets sent to me by Karl von Salzen from a bus in a junkyard:
