I've watched this thread with some interest. Here's my two cents:
I've been an offroader for 48 years, driving various jeeps, trucks, ATVs, motorcycles, etc. I've pulled military trailers and civilian Bantams on everything from washboard roads to the Rubicon. I've also been an avid backpacker, and after my knees weren't up to the task any longer, for many years my choice for camping on road trips was a BMW motorcycle with tank bag and saddlebags.
I learned long ago to tailor my equipment and my gear to my specific needs, to know the difference between a "need" and a "want," and to make reasoned choices. As a backpacker and as a motorcycle camper, one of my prime considerations was weight and volume. I learned, sometimes the hard way, that carrying too many "wants" made my life more difficult rather than less. As a jeeper, I learned that filling limited space with luxuries at the expense of spare parts could leave me stranded. As an owner of a Bantam trailer, I learned that the luxury of a full field kitchen and many of the comforts of home often meant paying the price of turning a challenging day of jeeping into an ordeal, but that often the price was worth paying.
Offroad vehicles and trailers are tools. The gear you carry should also be considered tools. Bear in mind the maxim, "If the the only tool you have is a hammer, everything looks like a nail."
If you begin to think that you must always tow your trailer regardless of the terrain and length of trip, you will always be at risk of turning a day of offroading fun into a day of difficult technical challenges you would not otherwise have. For example, unless I was carrying food and cooking gear for a large group, I would not take my trailer over the Rubicon. On the other hand, if I was spending a week or more in Baja, or taking day trips from a base camp accessible by dirt road or easy trails, my trailer is more likely to be an asset rather than a burden.
My Bantam trailer is now used primarily for Boy Scout campouts (new adult volunteers tend to come back when you make them comfortable on their first outing), and when offroading for base camp camping or extended trips when I have too many passengers to be able to carry more than extra clothes and MREs inside my jeep. Since my family seems happier when they have some of the comforts of home, the extra work and inconvenience of pulling a trailer accross difficult terrain is worth it to me. It would not be worth it if I were traveling alone or with one companion, because I have a more compact set of gear that allows two to be comfortable and well fed without using a roof rack or hanging stuff off the sides of my jeep. I have no need for my trailer in that situation.
