I was faced with a similar decision a couple of years ago. Here is my thoughts and experience:
My regular mission is flying from Flagstaff,which in the summer sees 10,000 foot density altitude, to Phoenix and back. … that is for my business, but wanted an airplane to use camping in backcountry strips also.
I ended up finding a corrosion free Hangar queen, which was a 206F model normally aspirated with a factory floatplane kit and Robertson STOL. I replaced the engine and all accessories, I went with an “I owe” 550 and a Voyager prop. My empty weight is 2000 pounds and useful is1600. … an H model would’ve cost another hundred thousand dollars or more and probably have had a midtime engine.
No problem off the pavement in Flagstaff in the middle of summer, I usually fly down to Phoenix with a near full useful load of coffee and cold brew, but return more than half empty, even when it’s 105° in the afternoon, it seems to hop off the runway pretty quickly, my main challenge is cylinder head temperatures, which usually in the summer has me limiting climb rates to around 500 feet per minute.
I initially thought I wanted air-conditioning and was going to get one of the remote ice units for the back. … I may be wrong but when it’s over triple digits, it takes a while for even a car to cool down, I wonder how much more comfortable you would be on the ramp with AC for the first 10 minutes anyways, … even with limiting my climb rate in 10 minutes or so im up at a much cooler altitude, … I never did get around to trying a cooling unit.
If you get an H model with a turbo and AC, you’re gonna have a very heavy bird, besides wing tips, you may want to consider a Sportsman STOL kit
