Electric stabilizers
I have a 2012 Wildwood 26tbss. It came with Lippert Electic Stabilizers. I an wondering is it better to extend them down as far as possible or block them up and keep them as close to the frame as poss...

But, Engineers!!! Looked up the formula for beam deflection, plugged in Moment of Inertia (.486 in^4, 2"x2"x1/8" struct steel), Modulus of Elasticity (2.9E7psi), 30" beam length and set 2000# at centre. The formula (if I've done it all right) says the deflection will only be 0.08" at the centre. 4000# would deflect 0.16". What this doesn't tell me is whether the beam will collapse at that deflection. But I hope not, especially with the original arm bolted to it.
I am not an engineer, so any comments appreciated.
Probably not, but to know for sure you'd have to look up the formula for buckling. However I would not expect 2000# to be dumped to that stabilizer either. To much "give" in other parts of the RV before that would happen, especially if you are following instructions and not attempting to use the stabilizer as a jack.
I like the use of the word "collapse". Suggests instability which is the mode of failure that would happen when an open section fails - it is typically by buckling. I think you also used the word "kinked" which is how the side wall of that open section would look when buckled.
For a non-engineer you acquit yourself very respectably, technically. :)
