Welcome to FRF!!!
and Congrats on having the only truly capable minivan to tow a full-height conventional travel trailer, the Safari/Astro minivan.
by the way, you say you have a 18' Microlite. the only Microlite with an 18 in the model number, is the 18FBRS and it's just about 20' long.
model numbers rarely are the trailer's actual length.
