Hindsight2020,
Have you ever worked on a Bo to do what I suggested? Your comments implies you have not. I have.
I recently worked on a V35B. Client had a back-up battery to a Castleberry AI in the rear, along with the autopilot computer and the yaw damper. Left the yaw damper in the rear but pulled the battery further forward. Also pulled the RCA WeatherScout (screen, processor, and antenna), ADF, (dead) back-up alternator and related wiring out. When finished a significant weight loss. Aircraft already had tips, so useful load (which I mention in my post) was already @ 3,600 (20/40/40/20 gas tanks). Completed 337 paperwork to add 20lbs in each side of the engine up front for 40lbs total in addition to factory 20lb nose weight (already had a three blade prop), and the CG moved a bunch. When the client flies with 4 people no one has luggage on their lap. After doing all this work the plane hit the scales and we re-weighed and computed the CG, not just modifying existing numbers the client already had. We leveled and re-computed every calculation. I continue to be amazed how inaccurate W/B numbers for many aircraft are, as they have not been weighed in years. Keep modifying existing numbers. (Pulling out dead avionics and other items DOES make a difference.)
What I stated was for a V35B. An A36 is obviously very different, as are other Bo models.
Single engine aircraft - there aren't many models where you're "going to stuff the baggage". Can you carry reasonable weight? All depends on passenger weight and a lot of other variables. Would the V35B I mentioned need to travel with 120 gal of fuel on every trip? Doubtful. Every pilot should have a W/B spreadsheet or an app with EXACT weight numbers so it's easy to compute on each flight. Most planes I put on (certified) scales the empty weight is rarely correct. When buying a plane - don't trust the weight numbers - get it weighed as a part of pre-buy.
re: Bo landing gear, it's tough and takes a beating. Easy to service if you know what you're doing and have the right tools. That's not typically where I'm spending time, unless it's replacing rod ends or adjusting what the last guy thought was set correctly. Uplock tension and a few other adjustments and you're good to go.
Re: Cirri, AD compliance is not an insignificant cost. Brakes are another item to keep an eye on. Cooling with the wheel pants on is something to watch. I don't work on Cirri so I can't cite specific examples, other than listen to my comrades (who do) tell me what they are billing their clients. For the Cirri pilots here, post what you're averaging for annuals and how many hours between annuals and let the readers draw their own conclusions.
