What we know from the latest medieval archeological research. The Somali Caravan transportation system was highly advanced and developed.
State leaders built many Caravan stations all over the interior of the country called ''Qalcaddaa'' to direct and control trade.
The Archaeology of the medieval trade networks in Western Somaliland
They were built in similar style pattern to the ones in the Middle east/Arabia as well. This robust caravan system was responsible for making Somalis extremely wealthy in what researchers describe as one the most successful trading networks in the world.

@Shimbiris have explained transportation of trade goods via camel caravans were ubiquitous in nature across the whole peninsula. Much like seafaring was for Somalis .
I watched the lecture. He doesn't seem to mention Somalis in the whole lecture, except 1 time in the mere passing mentioning the nomadic zone after talking about camels used for farming.. Does not mention anything about Somalis being technologically different from Middle East or not having camel caravans or the saddle not being able to carry large goods.
@40:00 He does talks about the difference between the camel transportation in southern sahara vs the northern sahara. He says that in the southern sahara they adopted the Arabian camel saddle which was designed for military reasons and instead they utilize it strictly for personal transport and don't use it for caravans or commerce. Other than that he mentions the spread of camel, camels used for agricultural (plow technology) in certain places and camel armies etc.
Also the type of Saddles Somalis utilized might just vary depending on use of animals, context or functionality much like anything else. Some could have been influenced by the decline of commerce that happened between 1600s-1800s following the collapse as well. There hasn't been much research on.
The main difference i would say is that Somalis did not use the camel for military purposes, they used it for personal transport, and for trade/commerce. Horses were breed and used for military riding. Somalis were prime regional horse breeders and they did not need to use camels for warfare. They used cattle for farming as well.
