paying child support while otr trucking?

ya im aware of the200 a week advance and 600 or .12 cpm during training i prefer to save money before going to use for the first month instead of taking the 200 a week advance that i'll have to pay back.besides once i leave my current job ill get probably 5 or 6 thousand from nh retirement since im not vested i'll get that money 2 weeks after i resign. dont forget the most important thing is getting a child support modification in paying support which will need home time at some point to do that in person at the court.in my case ill be making a little less while training then im making at my current job so i'll have to get a modification
