Anyone ever had half of the mounting bolts and nuts just fall off over time???

Are you towing your Fountain with the factory setup? Anything over 7500 lbs. requires a Weight Distributing hitch.

Hitches need to be regularly checked. Search "thisistank" 's posts about his Putnam just cracking in half. They are not bulletproof, and should be a regular part of your towing setup checks.

No way. Got a little 27' with aluminum trailer. No weight at all - 5500LBS. Most of the mounting hardware was simply missing. Amazing.

Replace missing hardware with grade 8 fine thread bolts, waskers, lock washer and red locktight. And better after market hitch!!!!

2004... chances are someone took it off for some reason and forgot to put everything back on... or forgot to tork properly... or like I've seen once, a thief started to take it off, maybe he was seen and ran away! I've seen that for real...

I put a torque wrench on my hitch bolts a couple of times a year after having one come loose back in the 80's. Every so often I find a bolt that is under tight

Don't be surprised if the holes in the frame are metric and the bolts are not metric.... IOW, the bolts can work loose..

They are not threaded holes. Just a bolt on the other end.

SDFever, those holes were probably never meant for a bolt. I know there are several holes on my silverado frame that just sit empty.

They probelly fell out when you brought that forklift home

Negative. All of the holes in the hitch frame itself are threaded and they are all the same thread. Got a new bolt kit coming from chevy. Most hardware on the street isn't above grade 8. Suprisingly, the oem bolts are 10. Thanks for all of the replies. Thinking that I was the only one this ever happened to was driving me crazy.
