It depends on you. We firstly recommend you not to cut the cabs or roof hatch, so we have some models that do not need to drill, such as E-Clima2600S, CoolPro2800/2300 suit for truck sunroof size, CoolPro2800B, CoolPro2800S and GoCooler series.
Yes of course, not only for truck cabins, but also KingClima truck ac units are widely used for tractors, rvs, construction cabs, forklift trucks, excavators, cranes, mining trucks and even for the cable cars in some scenic areas.
Usually for the hot sale models we have enough stock in factory, and we will delivery products in i working day after the payment is ready. If not enough in stock, the delivery time will be in 7 working days.
