I have mounted solar panels on all 3 TMs that we've owned (also on 3 different motorhomes). I always mount them on the rear of the TMs. However, my batteries are in the rear cabinet and I believe that your batteries are mounted on the tongue.
You want to run the wire as shown in the pictures below but when you get to the bottom of the lift arm, you will turn left and go forward, under the trailer.
When mounting the panel, there is no need to put holes in the roof. You can mount the panel using 3M VHB double sided tape. The attachment is over 20x stronger that screws in that thin sheet metal.
You just have to be sure to clean the area well with car wash soap (or similar), rinse well, let dry then clean the mounting spots on the roof and the mounting brackets with rubbing alcohol. Let dry. Pre-mark the place for all 4-mounting brackets (attached to the panel) and be sure that all 4 brackets are flat on the roof (bed the brackets slightly, if necessary). Place the tape on the base of the mounting bracket and then (very carefully) on the roof. Press each bracket down hard to the roof to activate the tape. It takes 24 hours to cure the bond.
Also, note the way the my brackets are orientated. The feet point out, away from the panel and the bracket are screwed into the SIDE of the panel with self-drilling screws. That way, the panel can be easily removed (for cleaning the roof) without disturbing the brackets or having the reach nuts & bolts from underneath. I like to use the type of brackets shown below. I drill holes the the small ears for the panel mounting screws. If you click on the 1st picture to enlarge, you can see the bracket mounting clearly.
If you ever want to remove the solar brackets, just slide a razor blade between the bracket and the roof. With a little patience it can be done without even scratching the roof. The tape remains gummy so you just run the razor one direction and "slice" a little at a time.
To make the job really neat, I always use conduit to conceal the wires on the roof and running down the side.
