If you 2 part each auxiliary winch back to the leg that will solve your stalling problem. Nice upright.

When I built my 550 I removed the interior to install the consoles and other equipment I placed 2 wires in side the roof console. I mounted an LED light in the area behind the switches and for additional lighting. Warning. It is difficult to remove this console very hard plastic snaps. It is easier to remove complete headliner to access

I agree the rear springs are not the best on a f550. I am building one currently, but we also add springs to the top and bottom of the mains. Have been doing this to ALL of our wreckers no matter the brand for the past 62 years. The manufacturers haven't realized where a wrecker carries its weight; behind the rear axle. The better the rear suspension the less squatting it will do and better steering. You are correct if is on a 60 ca/ with wheel lift at full extension going to have some issues. I have a 2008 F350 with a 6 ton single line wrecker with sneeker wheel lift. I am towing single axle tractors from rear, 350 box trucks from front and large SUV on wheel lift with no front end issues.
