Thread: OK, i'm new to this site, so please be gentle with me

I have a '93. 3.9 Dscovery with about 300K klm on it.
It has a rebuilt gearbox that whines annoyingly, a 10 year old John Davis chip, 2 1/4 stainless exhaust, Ulitmate suspension with Bilstein shocks,bull bar tow bar etc.
It has rust under each rear guard, the tailgate sill, and is appearing around the alpine windows.
It no longer holds its wheel alignment for long, although i'm told be mechanics that there is no mechanical problem to be found.

Question.
Is the rust in these areas conquerable or will I simply chase my tail trying?

If not worth the effort, I would like to update to a TD5 or similar V8.
My enquiry here is whether the diesel would be better for towing a trailer with up to a Tonne in it, or if the V8 with some work such as a Haltech and LPG would be a better choice. I'm sure the gassed option would be the cheaper to run.
I have some reservations re the TD5 following being warned off by a local Rover specialist, but there seems to be a lot of support for them on this site.

I use the vehicle for camping, surfing, hunting and fishing.

I would prefer to keep it given the economy (share market, not the disco) and having set it up reasonably close to need/want. I just don't need to spend 2-3 grand on it every year, which I have been. After a few years it becomes a false economy,comparative to the purchase price of a replacement vehicle.

The plus side of a replacement is more internal room, and less mileage on the replacement vehicle. That makes it a more sensible option to tinker with the mapping for a more reasonable economy (there's that word again. A contradiction in terms to a V8 Disco), and not losing the gains in a worn out vehicle.

I'll do what I usually do. Deliberate for 2 years then make a spontaneous and unrelated decision.
