Make sure its going on a air ride trailer. If you are not sure ask shipper if it will be.
Overnite,Yellow,Roadway are spring ride trailers. You mite give Mayflower or other reputible household moving companys a call and ask them if they do ltl ( less than truck load ). I know North American has a electronics division. Also make sure you put do not stack signs on your freight as well as fragile.
