Planning for solar installation this spring

My TT comes with a single Interstate SRM-24 battery. We camped for one season so far and never really lived off the battery in any of the campground except for maybe an hour where I didn't plug in shore power, and the battery indicator went from 4 lights to 3 lights.

This season we plan to camp at least 2 separate weeks without shore power. I don't want a noisy generator so need solar.

After reading on varies sources for a few days, this is what I'm thinking.

1.) sell the Interstate battery, and get two of these AGM batteries for 200 AH capacity: https://www.amazon.com/dp/B00S1RT58C/?coliid=I1D1MA2RB6OCWZ&colid=2AX6R5XMB9ZVD&psc=0&ref_=lv_ov_lig_dp_it

2.) buy two 100 watts panels like this Renogy panel: https://www.amazon.com/Renogy-Watts-Volts-Monocrystalline-Solar/dp/B009Z6CW7O

3.) get a MPPT charge controller, maybe this SolarEpic MPPT 30A controller: https://www.amazon.com/dp/B00ZV3I6OI/?coliid=I2NCX7KMV58EE4&colid=2AX6R5XMB9ZVD&psc=1&ref_=lv_ov_lig_dp_it

My TT has a under the bed storage area in the front of the trailer. The battery is current mounted on the tongue and there is enough space for two batteries there. So if I install the controller in the storage space, I think I can drill a hole in the floor and run the wires from the panels and to the batteries through there and somehow seal the hole.

What's the preferred way to mount the panels on the roof? I read of using 3M VHB tapes to tape the bottom of brackets to the room, then bolt the side of the brackets to the panels. I have never used VHB tapes and don't know first hand how secure this is. Would hate for the panel to fly off on the highway. If I drill the roof and screw the bracket to the roof, what's the best way to seal those holes? Silicone seal?

Another question is running the wires from the panels to the controller. The panels will be mounted near the rear of the trailer. I'm thinking run the wires down the back of the trailer, then underneath the trailer to the front where the storage compartment is and drill a hole in the floor to run the wires in. Is there any issues with length of the wire vs. power loss from the panel?

Lots questions. Never done any work on the trailer and never played with solar before. Thanks in advance.

What do you plan to do for power once the sun goes down. Those 2 batteries won't provide much in the way of reserve capacity if you want to watch TV or turn on a couple of lights. Cooking with electric is out of the question so you just need to ensure you keep your expectations realistic and have a backup plan for solar which likely will include a small Honda type generator at a minimum.
