The lifting roof actuators is nice as well but looks kinda janky to me. At least the internal one isn't too expensive.
Agreed. Nice to see 4WC modernize, but their electric roof lift systems don't impress me much.
The *exterior* actuators are not vertically-mounted so they "push" inefficiently, causing wear and tear and consuming more power than necessary. The design appears to still require the assistance of the non-electric struts (in the rear) to lift the roof. And the "scissors" track/guide which gets added to the camper interior only adds more complexity to the system, not to mention the space it consumes, while looking like a garage door system. I'm guessing the "scissors" hardware is necessary as a safety "lock out" because the exterior actuators cannot be trusted to hold the weight of the lifted roof.
The *internal* actuator is, in some ways, superior to the exterior, esp if inexpensive. At least the internal actuator pushes (mostly) vertically. However, according to the video, you've got to separately lift the back and the front of the camper, which requires a repositioning of the single internal actuator. I suppose repositioning is not not that big of a deal, if the price is right. But, does the interior actuator need to be left in "support" position while camping, or can it be tucked away???
Overall, not even close to the OEV or Supertramp solutions, IMO. But, at the right price, these solutions could be viable, esp the interior option.
