Keep in Mind: Some vehicles do not have a drain plug. In these vehicles, the differential cover must be removed to drain the fluid. A new gasket is installed and the proper amount of oil is then added.
As with the large tallit, assume that the tzitzit will be 12â³ (30cm) long. My personal recommendation is to make the tallit at least as wide as one cubit, whether that means choosing the stricter interpretation of 24â³ (61cm) or the less strict 18â³ (46cm).
Most all Trailers are classified to be either 6' Tall, 6' 6 Tall, 7' Tall, 7' 6 Tall, 8' Tall, 8' 6 Tall and etc. The answer to height will be one of these, but it's highly doubtful your trailer will measure one of the above exactly so don't worry to much about it.
