Hi! You have your work cut out for you! I would reccomend getting some bags that are used to transport live fish, a large plastic storage bin, and a bunch of 5gal buckets. The fish will need to be bagged in adequate tank water with adequate air. As few per bag as you can manage. Place all of the bags of fish upright in the large plastic storage bin for easy transport. If there arent many fish, the bags can be placed upright in a 5g bucket. All of the filter media & any plants/decor will need to be placed in bags of tank water as well- do not let them dry out. These can be placed in bucket as well for easy transport.
Empty the tank completely of water while gravel vac'ing. If there is any substrate (gravel, sand, etc), place this in a 5g bucket as well. If theres alot of it, you may need more than 1 bucket. You can place a drawstring garbage bag in the bucket first to keep everything clean & prevent spills.
When you get home, reverse the process. Add back the substrate, condition & fill the tank, add any plants/decor, setup the filters & media & get everything up & running. Float the bags of fish in the new water to equalize the temps & follow the 'drip acclimatization' process to introduce them to their new water. If your not familiar with drip acclimatization, google U-Tube for how-to videos. Monitor your tank conditions for atleast a wk or so afterwards to make sure there are no spikes in ammonia and/or nitrites- if there are, do water changes as needed.
I think thats everything but ask if you have questions or I missed something! Good luck with the move!!!!
