We have seen other Fifth wheels on the same level sites not use any wood blocks, just extend the levels a long way down. How do we know how far we should extent these?
Your title says you want to know how far you can raise the front leveling jacks, but the bulk of your question is about how far can you lower the jacks.
Assuming you want to know how far you can lower the front jacks, I have a 2012 Silverback 29rk without the electronic jacks, but I will lower the front jacks until I see the outer strut start to extend and then I pull the locking pins and lower the inner strut manually until they are about 1-2" from the ground and then reinsert the pins in the inner strut just below the outer strut.
