1-Open engine hood and stand on the support above the grill.
2-Telescoping heavy duty painters pole with a brush head. Wrap a towel around the brush , secure it using string or fishing line.
3- stilts, like professional spacklers wear.
4- fabricate hand trucks without wheels.
Have a welder make you two identical pieces that resemble a hand-truck. Place the blade under each front tire of the rv to hold them in place securely. Build them tall enough to clear the fenders, approx 5-6 ft fall. Then place and secure planks across the hood using the top of the metal hand trucks as your supports.
This is more secure than using two ladders and a cross plank.
5- find someone with a bucket loader tractor. Stand in the bucket. Have him lift you up.
