I don't know about you guys who =have= to use blocks. I know I've got AT LEAST 4 feet of travel on my landing gear; 2' on the motor and 2' on the extensions. IMO, the only "blocks" you should have under your landing legs are weight pads to keep them from sinking; =maybe= 2" thick, max. I =do= boondock and, at my usual spot, need nearly 20" to get level after unhitching. I run my legs down to about 6-8" from the ground before pulling the extension pins, unhitch just far enough to stay plugged in and drop the nose to level. No matter how well chocked, having landing legs blocked more than 6-8" scares me.
