Plugging into house?

[EagleScout-USA]

When plugged in at home, should I:

1. plug the trailer 30 amp cord into the adaptor (reducer) then to a standard extension cord which in turn will be plugged into my regular home outlet in the garage, or

2. purchase a 30 amp extension cord (25 feet) and connect that to the 30 amp trailer cord, with the adaptor (reducer)then plugged directly in to my home outlet

I realize not to use any items with a significant electrical draw while not plugged into a 30 amp service, but I want to ensure safety and avoid electrical problems by ensuring I do this right.

Thanks!

When we first bought our trailer I bought a 50A plug to match the inlet on the trailer. I also bought a heavy duty 25 foot extension cord, cut the end off and installedmy 50A plug. Makes a simple 20/30A extension cord.
