I would also suggest that you consider putting her up on 4 axle stands, this will not only stop pressure and possible flat spotting the tyres but will relieve the pressure off of bearings and bushes which can be affected by just sitting their under load for a long time. This will put load on the bottom springs of the front suspension, but should be ok. Personally I would rather replace those than than bushes and bearings.
Other views on this would be worth while.
