I have refrained from posting here as I am a Casita not an Oliver owner. I joined this site to learn from other fiberglass rv owners because we share a lot in common. I posted a private message to the moderators but will now take a public stance due to your increasingly aggressive behavior.
Your post about weight to this forum, in my opinion was not appropriate, you should have been dealing with the Oliver manufacturer and allowing them the time to resolve your personal issue instead of trying to force them to answer on this forum.
It is not Oliver's responsibility to determine what tow vehicle you have, plan to have, want to purchase or don't want to purchase. That is your responsibility just as it has been the responsibility of all of the rest of us.
If Oliver or any other manufacturer post a base price and you start adding extras but do not have the intelligence to realize that extras are just that and extras add "extra" weight, that is not the responsibility of Oliver.
Please check your ego at the door. You are not asking questions, in my opinion, to get answers but to show others on the forum how "smart" you are. I find your aggressive behavior offensive.
