HI Herrblick,
I've just been throught your same question, I have a RRS and I did have a D1 300tdi, Whilst at the local dealer a few weeks ago now I saw a new Defer my wife suggested taking it for a drive, which I did. Well it was like going from a tractor to a limo, everything I asked if it had the answer was repeatedly no. And yet the Defer just had something, something that sucked you in, a character, a personality all of its own.
I couldn't part with my RRS so I sold my D1 which just hasn't got what I was looking for and I bought a 2001 Defer, it has a full LR service history a few little extras, bull bar winch and a dual battery system and thats about it, plus it has got the TD5 motor which I want to try out.
I'm now in the process of getting it ready for a trip up "The Gunny", Kununurra and beyond later on in the year. I don't doubt that the RRS could make it in comfort, however when I'm relying on two bits of plastic I bought for $15 off Fleabay to protect my radiator I think I'm in the wrong place. On the Defer the doors don't shut properly, there is a biro tip stopping the rear sliding window from rattling, the axillary battery is rooted, I have an incessant diesel leak from the pressure regulator on the head which isn't going to beat me and I've got to buy some new tyres, after all that I love it, great decision on my behalf and who knows if I like it enough when the new Defer arrives if it isn't to radical a change I might buy a new one.
Buying a second hand defer will give you that insight into whether you will like one or not.
