This week I had a few incidents where the limits of my trailer were reached. I chose the step deck because of the increased versatility over my previous car hauler trailer and that’s been 
proven true. However, there are limits with this type of equipment; namely the lower clearance and two separate decks. It’s the former that gave me some trouble last week.
I’m very aware of the clearance issues since my last trailer was low to the ground, but I mostly transported vehicles to paved and level parking lots. In the open deck segment of trucking, most of the pickup and delivery locations are off road and not level.

I delivered to them on Wednesday right before the big east coast snow storm in North Carolina. I was told that there was a hill, but when I got there and saw the roller coaster (I may be exaggerating) I knew that I couldn’t make it down without tearing off my tool box and ramps that hang slightly below the frame of my trailer. Thankfully, there was an alternate way in and I was able to deliver my load that way. A few hours later 8-10 inches of snow fell here so I was glad to get out before it hit. Who knows, I may come back, but it will be with my sled...
There's no perfect trailer. There are some that can do many things, but not everything. Whatever kind of trailer you pull has it's own unique limitations. I advise you to learn and be the expert on your particular combination.
