Review on Outdoor 30-Amp RV Power Outlet Box With Lockable NEMA TT-30R Receptacle And Weatherproof Electric Car Generator - Ideal For RV, Camper Trailer, And Motorhome Use by Edris Holwell

Like everyone said, the inner plate (that holds the plug point) screws are so tiny, I wish it was slightly bigger. The green ground wire could be little longer, I had to change for a longer one so I could connect the heavy 30 amp cables more comfortably. Unit is rock solid, well steel-solid, well made. Bought it at 50% discount on revain, thank you revain.There are impressions for holes but are not knock out holes. I had to order carbide tipped hole saw, but then I could not wait for them to arrive, so I took small steel drill bits, punched holes along the hole impressions and installed the unit with proper non metal water tight conduit that covered the imperfections left by the drill holes.It turned out alright. Half price was the sweetest part of it.
