Looking to install a tripplite pv1000hf inverter in my 1997 GMC Surburban. Considering installing a second battery to power it independently. Questions are: Other than inline 175A fuse, what OL protections should I use? Would like to install on separate switch in-dash that only powers the unit when turned on (regardless of ignition switch). Thoughts? Do I need a dist block? If I install a second battery do I need a larger alternator?

You wouldn't NEED a better alternator or a d-block. Just a heavy gauge fused power to the inverter. It wouldn't be a bad idea though to use a battery isolator. That way when your car is on it charges BOTH batteries but when the vehicle is off and the inverter is on it will ONLY drain the ONE battery intended for the inverter. This way you don't risk draining both and needing to jump your vehicle.

Noting that dual batteries need TWO fuses (one at each end) unless physically "protected".
And IMO definitely a battery isolator - that's to increase battery life if nothing else. (2 permanently paralleled batteries generally require FOUR battery replacements during the time you'd normally have to replace only ONE.)
If you have a charge lamp it can be as simple as adding a relay (aka the "UIBI").
Otherwise a cheap voltage-controlled battery isolator with te characteristics you desire (never diode isolators!) that drives a relay sized for your requirements (ie, don't get a 200A isolator, get cheaper 10A or 80A isolator and add your own relay).
My inverters would be switched via relays unless they have some remote on-off function.
Protection of the inverter's battery is through the inverter's low-voltage shutdown if fitted and suitable, else a separate battery protector and maybe relay. (Same as a battery isolator but set to lower voltages.)
