Black Walnut trees sold as lumber is VERY expensive. Some trees sell for over $1,000. Check if you can sell the trees.
That is a myth..
Lumber mills do not deal with homeowner trees due to high probability of metals like spikes, nails and even steel fence posts being embedded inside the tree. Not to mention the cost of dropping and hauling one or two "prime" trees of any type makes it not a worthwhile adventure.
Even if you drop and haul your self to a mill, the cost of one blade will sink any hopes of getting any profits out of that tree and many mills will upcharge greatly even if they don't hit anything.
Heck, I have a 100ft tall black walnut in my back yard, 36" across at the base, might get three 8ft straight enough sections if cut carefully. Worth more as firewood if you figure in the cost to drop, haul and pay a mill.. And yes, I can drop it, I can haul it but my time is worth more than the time that it takes to do all that.
Something else to consider on lumber, very few people or places are willing to pay anything for non kiln dried wood of any type.. So, to maximize the selling price you also must factor in the cost of kiln drying.. They don't do that for free..
If I was in the OPs situation with selling an moving in the near future (yr or less?), why bother with any covers? Seems to me even one yrs worth of weather exposure without a cover is not going to harm their RV.
