Need help and advices on buying FL csc

I am tempted to purchase a used Freightliner Century or Columbia with 14l Detroit engine and shipped it to Kuwait.

So far we don’t have American Big Rig and all what we got is European truck. They do fine in the 90s but the newer models have tons of problems due to heat and dust etc.:

My questions are:

- How can I convert truck with12v. To trailer with 24v.
- What are the necessary spare parts do I need to keep in door.(at least for a year)
- Where to buy parts for reasonable price aside from the Dealer.
- As an alternative, if I get a better deal with MBE4000 engine, can it handle extra heavy load as a Detroit s60.
- Last thing, can a single axle perform as good as a European single axle if it geared like 3:90? Or should I go with a tandem


I truly appreciate your help

 

i am not a fan of MBE neither but nearly everywhere a side from the US is a loyal fan.
CAT engine parts price on ebay drove me away .

the legal weight on a single drive axle is nearly 29k lb. total GVRW thing is limited to 100k lb regardless of how many axles . actully with a tandem you loss some load weight as it heaver .

 

thanks master Pablo, i chosed Freightliner Centrur as you once posted it is popular in Russia. though i wonder how it will do when the weather near 50 degree (120F) lol
