Just a thought. A 18,000# 5er will have a 3,600# plus pin (20-25%). Many of the older trucks had a max 11,500# (give or take) GVWR and the SRW was 9,900# max. My 2004 F350 is around 8,200# with us and stuff (CAT Scale) and with a 11,500# GVWR leaves 3,300# for my pin. The GCVWR is 20,000# for diesel and less for a gas engine.
The math just does not work for a F350/3500 on a pre 2005 model year.
For reference, at 10 years old the dealer still wanted $20,000 for my truck. I ended up writing a check for about $15,000.
An 2015 F350 DRW diesel is 14,000 GVWR and about 32,000# GCVWR
My 2004 F350 DRW diesel is 11,500 GVWR and 20,000# GCVWR
For a 18,000# trailer that is a world of difference.
You will have to search long and hard to keep to your budget.
