2002 Duetto - suitable Khyam awnings

We have a Khyam Excelsior awning that we used with our former M/H (a Swift Sundance 530LP) - it looks on the face of it that this is a good fit for the 2002 Autosleeper Duetto (Transit-based) that we are about to get. The Duetto has a Fiamma retractable sun awning fitted, which I guess has a slot for Kador. On the face of it this looks like a workable combination given the height of the Duetto - does anyone have experience of this combination (or similar) of van and awning? If there are problems with this combination can you recommend a suitable awning that uses the same erection principle as the Khyam Motordome - ie a central "spider" that can be put up by one person - I have rheumatoid arthritis and when I am flaring my partner will have to put the awning up by herself.
