Well, I just checked this thread and I see I am being blasted.
Okay- I don't think you are being blasted, I think some of us may have been carried away, but they just trying to add their own experience. Like YOU said before- don't do anything that doesn't feel safe. For example, I trailer my BX with loader and backhoe on a 16fter with loaded tires, all equipment, accessories, etc behind my little S10 blazer. I feel it pulls and stops ok on flat roads. I added WD and sway bar just because it pulls and stops better with it. I figure I have close to 3k lbs plus weight of trailer. In fact I am pretty sure I "might" be over the limit a few times with it as for the truck limit, but it handled just fine with good driving habits and top maintained equipment, and whole lotta of common sense of respect.
I believe you will be fine, in fact pulling better then my S10

. you have a wider stance, longer wheelbase then the S10 so you "shouldn't" have sway issues with your L. Adding a WD bars will do a world of difference with the equipment you have and want to use.
