I've had a few LT's over the years.
If I were to go back to one, then it would have to be one of the last LT 35's.
The 2.4 TD, with power steering. (Maneuvering an LT at low speeds, without PAS is not much fun)
They sit fine at 65mph, with more space, and carrying capacity than a T25.
The late 2.4TD's return around 28-30mpg on average if driven sensibly.
Like the T25, the 5 speed manual versions have a dog leg gearbox.
They are a good van, but obviously pretty dated compared to modern vans.
Westfalia did an LT 35 Florida, which is a well equipped van, but like T25 Westy's, LHD will be the drive side. These seem to change hands from about £7k up to £15k for really top examples.
If you are looking for a panel van to convert, I think you'll find that most on offer will have done pretty big mileages by now.
They were the van of choice for market traders during the late 80's and into the 90's, and beyond for some, because they were very square shaped, so load volume capacity was good.
You definitely feel like you are driving a much bigger vehicle, compared to a T25.
The cab area's are nice and wide, with plenty of room, but where the engine on the T25 is at the back of the van, with an LT, you are literally sat on top of the engine in the cab, but insulation is pretty decent, and engine noise isn't normally an issue.
If you wanted a retro van, rather than the modern equivalent, then they are well worth considering, if you can find a good, late example. (1992-95)
There is a decent facebook group for them, if you go on there, you'll probably stand a chance of buying a vehicle that's been owned by an enthusiast.
Hope this helps
