Anyone got experience of working on these? I'm advising a relative

I've done all the Googling about the pros and cons of the basic idea,

are
likely to have been at that time as regards insulation etc. Do they
have
timber rafters and joists between which celotex could be fixed? I'm
thinking exterior insulation panels might be prohibitively expensive,
and probably not as effective.

Oddly enough, I posted about this a few weeks back, since I know someone
who lives in a (probably older) but similar beast. External insulation
seems to be the way to go to avoid losing space.xxxx

so you havent the hassle of dismantling it, wire and pipe routing and
lots of coldbridging,
you mean to glue kingspan to the outside
and then weatherseal that with another layer?

Yup basically. Many of the modern homes have a textured render finish of
some sort, so one can slap foam boards all over, and render over for a
similar effect. From what I have read they have also made dispensations
in the legal maximum sizes of mobile homes to allow for the insulation
of existing maximum sized ones.

I wonder how this affects the roof overhang/guttering etc
