The G coupler is a godsend IMHO - I did specify the remote grease kit and find it a boon particularly when away on a trip -- I agree it is necessary to get underneath to check the various nuts and bolts and to see no excess grease is likely to get on the disks, but that is NOT necessary every time you grease the kingpins - I get under mine about every three months and find that is perfectly adequate. NOw maybe if you only did 1000miles a year or so it would be different, but mine is no garage queen!
