My experience is completely different we had a large fleet of LPG pro5 doosans mainly at 2 customers they were a nightmare transmission failures wiring loom failures and the GM engine lol cooling faults spark plug threads failing wheel bearings failures the list was as long as my arm they were serviced per doosan intervals using doosan parts (we were a doosan dealer). Then the B series electric trucks we had the amount of controller failures we had was tragic. They were such a good truck lol our biggest customer insisted we either went with another make or they would go elsewhere and I'm glad to say we did
