I clicked to see if it was my old one. Sorry to hear of your purchase. Good luck, lol.
I did extensive roof/lift repair and never got it quite right. There are lots of pics of it , some here

The Heco lift system is awful. It has torsion bars inside the poles that run along the top. These "sag" over time and need to be clocked if the roof is not neutrally bouyant [sp]. It is a six sided clock inside, so is big twist if you do and huge section of canvas will need to come out.
Yours looks pretty straight, but mine skewed off to the left when raised. I never figured that out or got it fixed.
The Heco crank is made of pot metal and is good for 30-40 lifts then is ruined, unless your roof torsion bars are doing their job. Mine took a lot of force to raise.
The wood rots where the torsion bars are bolted in, and I can see yours have issues and seem to have twisted. The tension will arch the rear of the roof up. It should be flat, but the aluminum trim will bow up in the middle. This is from the constant tension. Eventually the wood gives way and mounts twist, faster if there is rot.
Best solution is to throw existing roof in trash and make your own, very light, roof and use accordian [ok, spell checker not working today] braces and gas shocks to hold up the light roof, this would lower your overall profile also. Sounds hard? Fixing that Heco roof is harder.
One cool thing I did was to raise the sink/stove counter top. This gave me more storage under the counter and since I did not cook with lid closed gave me a more normal height counter.
I sold it bc I hated the issues with the Heco lift and all I ever saw was all the work I put into it that I never really was able to finish or get right.
I have more pics of the actual renovation (not the mandatory repairs) somewhere.
