Thanks for the pics
How did you manage to revive the plastic trim on the outside?
What will you use for insulation on the inside?
I used this
Thermoliner insulation from Harrison's Trim Supplies. You get 8m off the roll Thermoliner sheeting which easily provides enough insulation for a short wheel base van.

and know it works because condensation was dripping down like rain before I stuck it on the roof, but one layer of thermoliner stopped it completely.
You can also get thermoliner like stuff off ebay - the sort without the silver foil is cheaper. But I found another layer wouldn't stick to it properly, wheras with the silver foil covered type you could stick another layer over it.
