I use mine (SGPRSMD trailer) often, at least several times a month, year round. I use it in fair and foul weather. Unfortunately I don't have all of the curtains. The heater does keep things comfortable in the winter. The controls and equipment are user friendly, although interior space is not for the tall or portly. With both wings and rear panel open, work platforms down, there is ample work room. Climbing in and out gets old, I have the boarding ladder for the back, and use a short section of an extension ladder on each side. The engine and dynamotor is easily serviced, accessible from the sides and bottom. At the present, it remains parked as I do not own a truck-tractor to pull it.
