Hello - my husband and I are buying our first 5th wheel. We have had a Class A motorhome for the last 10 years but now want a toybox. We are mostly looking at (used) 30-35 foot Weekend Warriors and Alfas. We have no idea what type of hitch to get. We have a 1999 Ford F350 Diesel Powerstroke (we plan on getting a chip installed). Any suggestions on the hitch or the chip? Thanks so much!
