Cub cadet hydrostatic. Has custom hitch on front that releases side to side and in and out for hooking up. Custom tow bar :) Works great!

My 1943 Clarkat B works great, and as legend has it, will handle anything up to 80,000lbs.

I use two TSIO 360AB engines
 

I own Potomac Airfield. www.potomac-airfield.com

Our T hangars go for between $500 and $900+/mo.

At those prices, I'd have to be out of my mind to rent a hangar!

Actually, ...

1. I am too lazy to move it around in and out of a hangar. What, 3k lbs empty?

2. Modern paint/interior materials just don't wear out like they used to.

3. I find it hard enough to find time to go for a whirl.
A hangar would add another impediment to just 'going.'

4. I get my pick of tie downs. I'm sleeping with the owner's wife.

5. I face the schnozz (forward engine) NORTH, so
a. the angle of incidence of sun on windshield is 'behind,' = no real wear, and
b. snow/ice melts faster with tail facing south.
c. Washington DC climate is NOT Novosibirsk OR Abu Dhabi.
I wouldn't say 'mild.' Summers are hot.
Lots of hot air from downtown.
I think it actually creates a micro climate inside the beltway.

6. Did I mention I am lazy?
