i am about to do the same and the advise i got off of RC was to get the sand out if you move it with that sand you must be the hulk because with the water, tank and sand it is really heavy and with the nice bouncy truck you have a better chance of breaking out the bottom. i have heard to remove your rock and livestock drain your tank until there is about 6 in in there. next mix the sand alot get all of the HS gas and trapped gunk out into that water. then sipon off that water while pushing the sand away from the corner that you are siponing from. scoop out the sand place in buckets and put it back in the tank when you get it situated at the new place. the sand will stay moist enough to keep the sand alive so it should work out for you.
