Good on you for cancelling that trailer order. And good on you for learning from that horrible experience you had in that previous crash.
Everyone who's posted replies here have one thing in mind...safety. YOUR safety. Otherwise they would not post their opinions. There's a wealth of advice offered here. There is absolutely no reason for you to feel as though you are dumbasses. You came here seeking advice, it was offered, and you heeded it. The way I see it, that's using wisdom.
Go back to square one. Start a new trailer search. Ask for opinions here BEFORE you commit to a purchase and/or use the SEARCH feature to research prior posts about any trailer that interests you.
And God Bless your family for your service!!
