SWB Patrol Specs

I'm afraid 'The Decision' is going to have to be made sooner rather than later - do I:
a) Keep my current 1990 SWB Pajero and pay >$1000 to get whatever is wrong with 5th gear repaired

b) Sell it to a gullible salesperson, and buy a similar sized or smaller 4wd

c) Sell it to a gullible salesperson, and buy something just that bit bigger, to allow me to legally tow a horse float (1500kg) when the time comes - around 12 months away

d) Sell it to a gullible salesperson, and buy something wee until I find my ideal vehicle

With this in mind, I ask: What is the towing capacity of a SWB Patrol (late 80's, early 90's)?

Any other productive comments would be appreciated...
