Prado Suspension Upgrade

Thanks to those who previously assisted as it's now down to the wire. From what I've gleaned, it's down to either old Man Emu or Tough Dog. Friends at work reckon they'll never fit anything else other than Tough Dog. Then I saw a section on here of people who wouldn't have Tough Dog, even if it were free. So what to do? As a reminder, my 120 GX turbo diesel 2003 Prado is fitted with Toyota bull bar and Superwinch. I want to raise the vehicle 2-3 inches but not have the lift eaten up when attaching my camping trailer with it's ball download weight of between 150-180 kgs, not to mention the Engels and other equipment in the back of the vehicle. And not to have the vehicle skitter all over the place and be too hard a ride when not towing. I want to spend around the $2,000 mark to fit the appropriate suspension to the vehicle. I've refined my search to these two options and want to get started soonest. Thanks for your help (again!)
