This thing is beefy and not just for temporary purposes. We are building a garage/ shop and needed an easy way to install outlets to power the rv (30amp 120v), a level two charger for our plug in hybrid electric vehicle (uses the same outlet as a 50amp RV), and any random 120v items. This fit the bill perfectly and has circuit breakers pre wired in the box that are handy for the occasional nuisance trip from the RV when too many random things turn on.
This thing looks as durable as many rv park pedestals and would also work great outside. It has a NEMA 5-20R, TT-30R (for RVs not welders or driers), and a 14-50R. It comes with an adapter to relieve stress on things plugged into the household outlet, a key set, instructions, and a lock. It also has punch outs on all sides to pass wiring through for almost every use scenario.
Although shipping took a while (about a week with a delay), I believe the quality construction is worth the wait. Overall I am very satisfied with this product.
