OK! I will start with questions.
1. Is your charge line between truck and trailer adequate? If so, then getting to work and from work to camp site is not an issue.
2. What inverter is in the rig? What RR is in the rig? Look at the data plate. My Samsung RF18 sips at 3 amps. Some do sip a little more.
Our MH has the 2 GC2s at 230ah and a Tripp Lite rv1250ulhw inverter/charger.with nothing running but the RR (and parasitics), we last 10-12 hours, with outside of 75 degrees, in the sun. Fridge stays 34 and freezer at -2.
New batteries should be no problem. If work day exceeds 10 hours then maybe go out at lunch, check and run the engine or gennie for an hour, if possible.
Have fun. It will work.
