Agree, partially. The larger Black Series rigs are not like our previous AT Chaser and current AT Teardrop that could follow our Jeep, on 37's, to 90% of the places the Jeep could navigate.
That said, our HQ-19 has proven to be fairly capable- for its size. We don't hesitate to take it "off pavement" and drag the HQ-19 on any moderately difficult and/or steep trail as long as the rocks and steps are smaller than 12"-14", there are no tight/narrow spots, and the trail provides adequate traction. (traction is king when pulling a heavy trailer)
As stated, these trailers ARE heavy- GVWR is 8.900 lbs- and way less maneuverable than a smaller trailer. If you aren't careful, you can get yourself into a pickle that makes for a difficult self-extraction. Compared to when we are pulling our teardrop, we are much more thoughtful and deliberate when choosing which trails to tackle with the HQ-19. Even going up an easy trail, the HQ-19 is like dragging an anchor uphill.
Even with its limitations, our HQ-19 has allowed us to access camping spots that are much more remote than I would be comfortable taking a similar sized trailer with less robust suspension, lighter frame construction, and less ground clearance. The biggest advantage we see for these larger trailers, is the ability to access and enjoy semi-remote areas in comfort. (Especially true when inclement weather sets in- indoor shower and head and indoor cooking. Our main issue with our teardrop, and the AT Chaser, was lack of area to weather out a storm. We once spent about 24 hours in the tent of our AT Chaser waiting for weather to clear. We've found that camping, in the wet soggy conditions, is much more difficult- even when the tent platform is elevated or the sleeping area is enclosed.)
And yes, we are in agreement on the red bars. We don't rely on the "red bars" to protect anything. They definitely aren't a heavy rock slider that can be used to pivot the trailer around large rocks/obstacles. We view/use them more as a limb riser than a rock slider.
In the end, seems all our overlanding equipment selections requires some kind of compromise. I've yet to find any piece of equipment that is cheap, light, provides ease of use, is indestructible- no matter the abuse I subject it to, and flawlessly performs independent of operating conditions and/or operator ignorance, etc.
Enjoy the rest of your day and safe travels!
