To Offgrid
The water heater was drained.
Today I went out and took an eyeball calculation of the mass on the left and right sides. Yesterday it seemed to be more massive on the drivers side, now I'm not so sure its hundreds of pounds more (especially with slide in and closer to center of gravity). It would be nice to know the actual weight difference side to side.
They do seem to gross weight these things close to the axle weight limit, and the stress from a WDH especially under driving conditions does not improve the comfort zone
Although it is mostly an aesthetic problem, I too have some degree of concern for metal stress, bent frame and etc. However I'm thinking it is more likely a deformity or loss of elasticity of the rubber cords inside the axle tube that might be the problem.
Best Regards
