My solar panel lifts controller switch is in the same compartment as my charge controller. It makes no difference where I'm at, as long as the panels are pointing south, I get about 40% increase in energy, according to the display on my MPPT controller, when I tilt my panels to the correct angle.

I have dove the math many times (Iโm a NABCEP certified installer), for both residential installs and RV, water pumping, etc. Calcs on an RV are very difficult to really be accurate with, since you are always in a different place and always positioned at a different azimuth. 40% might work out on paper for perfect conditions IF you always had your RV parked in the same place, at the right orientation and IF you actually tilted the panels every time you could. In reality the gain is much less than than 40%. Thereโs a good reason nobody uses trackers and tilt adjustments anymore in residential and commercial installs. It just makes more economic sense, if you have the space, to add more panel to make up for the losses of a less than ideal tilt (or azimuth). By all means if you donโt have the space, tilt and azimuth adjustments are about all you can do.

Agreed on the tilting panels, unless you are planning on staying in one location for a long time, it is unlikely that you will end up tilting them. Easier to add more panels than dealing with tilting.
On closer inspection, are your mounting brackets covering some of your solar cells? If so this can have a surprisingly large impact - reducing the current from ALL the cells in that string. It may be worth getting some narrower extrusions.

Tilt lifts can be helpful if you donโt have anymore space on your roof. If you have the space, just take the money you would spend on the lift and buy another panel or two. One more panel will make up for what you lose having them flat. Plus, you never have to get up there and adjust them. Thatโs the strategy residential installs use now that panels have done down so much in price.

That's a really clean looking setup. I agree with the others though on the concern over the covered cells. Can you turn the connector brackets over? Put the L so it goes down the side and wraps under the panel. Then put screws in the panels from the side.
