OK, I just had to call Liberty Mutual at lunch time... .....
I am covered but was not explaining it correctly.
It works as Troubleshooter and Harvey say above BUT my $107. 00 per year policy on the Cougar covers Comp and Collision when attached to one of my tow vehicles in ADDITION to the coverage I mentioned above when it is not being towed (tree limbs, baseballs, wind, hail, dead fish in drawer, catching the awning on fire, any of the before mentioned catastrophes even if performed or caused whilst under the influence...

)... ...
So apparently insurance on RV's in Maine is relatively cheap... ... ...
To recap...
If my trailer swings out while underway and swats an oncoming DuraDud then the DuraDud's damage will be covered by my tow vehicle liability policy.
If my poor trailer gets damaged while swatting the DuraDud then the $107. 00 per year Cougar policy covers the damage to it.
If the Mega Cab is damaged by flying debris from the Disintegrating DuraDud then my trucks collision coverage will pay for those repairs.
If I hit a Furd you guys will all pay me if I take it out, right???Oo.
That makes sense to me now.
Mike.
