Noob west coaster with tard questions

Hi im antonio Im new to the forum and Im buying a truck in march or may been looking at 08-11 dodge 3500 6spd.
Anyways I got my cdl last month been driving flatbed (tow truck)for about 2yrs but im trying to start my own gig hauling cars. Ive seen all sorts of guys in cali doing it most i see with only CA#s when i doit i want to go interstate.
the question i have is for my ifta permit do i get one for every state im willing travel to or just Ca?

im also looking to get a new kaufman 3-4 car to have zero issues im iffy about used equipment i dont mind financing it either but while trailer is being built could i still obtain my required permits and authority? Or does trailer have to be present? Reason why i ask is id like to bring a load back on my brand new trailer back from nebraska to cali to not just come back empty or do i pay ($1500) to have it delivered?

dont get me wrong people id buy a used trailer but only from a former owner operator that is knowlegable about his equipment and give me part#s for specific parts that i should address when i need to service it not trying to come off as a picky s.o.b. But i know equipment being in tiptop shape is key especially if your trying to make a name for yourself (clears throat) i dont wanna be that guy that has to call the customer and postpone due to faulty equipment

insurance wise my cost is 12k a year but im going to pay half a year to have a good 6months to recoop $$$$

fellow hauler buddies shed some light over here

 

Ugh i really liked the dodge 6spd

Yes i heard the same about kaufman which is sad because i thought they were legit #### for $13-15000 i thought that was a deal compared to sun country $22000 and bigtex $18000
