former army vet now working in the HD field

Hey everyone, im a former army vet of 9 years and have my own dell rugged book I purchased due to my unit only having dinosaur MSD v2 diagnostic laptops that couldn't keep up with current software. I've been out of the service for a year and a half and am looking forward to reading all the great info on here. I used CAT ET a ton in the army and would like to get into using the civilian version along with cummins insite and other common programs used in the general engineering world(work for a general engineering company now) im going to be looking around and researching quite a bit on here, but if anyone has any good knowledge to spread on heavy duty and construction equipment programs and possibly good deals on comm adaptors like the dpa 4 or 5 or cat com III, it would be greatly appreciated.

Great to be here and looking forward to seeing all the years worth of knowledge and info on here!
