Compact-II's have a quilted synthetic leatherette over thin foam for the inside liner, but that's about it. Don't count on anything in an FGRV to provide much in the way of insulation (Unless it's a four season
BigFoot that is)
Be sure to put the top UP and inspect the top boot for any damage, they can be very expensive to replace. Most Jr's are fairly minimal for appliances but, if it has a
refrigerator, be sure it actually works and gets cold.
Also check the
tires for age dates. Anything over 6-7 years old needs immediate replacement. Ditto on wheel bearings, verify that they have been repacked if it's a long tow home.
