Try pushing your tires up to about 37-40psi. They'll sound a little harsher but that's all.

If you're going to install a deep cycle battery, why keep the original battery at all? That's extra weight you don't need. And if your recordkeeping bears out you could maybe take the belt off the alternator and run without it, if the solar panel pumps enough amp-hours back in when parked. NOTE: for the sake of recordkeeping, fudge the numbers super-conservative by running the HVAC blower on HIGH and the radio and lights all on the whole time you're recording.

Keep an alternator-included length belt in the vehicle, just in case.
