This Review of the BMPRO JHUB J35C RV-POWER MANAGEMENT (JAYCO FD19) addresses the JHUB system installed in the Jayco Conquest FD19 Campervan / Motorhome.

The JHub system overall would deserves a 4 star rating, but the J35 AUX charge mode disappoints (1 star) and hence I can't give the comprehensive system more than 3 stars.
Considering that Jayco and Setec are in a system development partnership and that none of their Engineers are accessible to us is a disappointing outcome. It takes lots of emails with their respective Service departments to slowly get a picture of what's in the box. I can see no technical reason why the "in vehicle charge mode" for the RV house battery should be any less powerful than AC charging mode from the grid. The JHub has been promoted as an advanced technology innovation that makes system modifications fast and easy (via Tablet). What these companies don't seem to appreciate is that there are 1000 members in our owners group and we probably meet thousands of interested people while we camp. I had a few people stopping by and ask me how satisfied I am with the van.
The BMPRO Miniboost is a necessary system supplement not installed by the OEM. So I bought it as an Aftermarket upgrade. On its own performs quite reasonable at 15A and that with Jayco's original thin wiring for the J35-Aux Input (someone else called it flimsy). On its own I recon the Miniboost seems to perform better than the thick wire Redarc bypass that Jayco has installed to boost the JHub supplied by BMPRO.
BUT The weakest link is now the J35's charging algo. What I would expect is that AUX charging and Solar charging via J35 work in tandem all the time full blast until the Battery is at least 80% charged. The currently implemented charge source priority & activation algo that tests loads should only kick in when the battery is nearly fully charged (if at all).
The J35 seems to often give solar charging preference. However with a Miniboost installed in a FD19, Solar is always the weaker source compared to AUX (15A constant vs 9A max). Imagine getting 15A+9A=24A most of the time. We would be laughing on our road trips. I am still prodding Setec Service for more answers on how their algo works and real answers of what can be done to meet or needs.
The sad thing is that none of the companies have allowed discussions with their Engineering departments. Service passes on our emails, but as far as I am concerned they go into a black hole. Not good enough for the dominant mass manufacturer of Australian RV's and their System Partner, but the JHUB will be a great system once it matures.
