Info On 1968 GMC Custom Camper Special

[Geno]

Two years ago I purchased a 1968 GMC Custom Camper Special. It's a 2500 3/4 ton longbed with a 6.7 396 V-8 and has power brakes,power steering,air conditioning and 3 gas tanks. I have been able to find nothing as far as how many of these rare trucks were made. There's alot of chevy info on the net,
but very little on this year of GMC trucks. I am looking for original specs info and how many were produced. The only info I've been able to establish is:
In 1968 Chevy celebrated their 50th year truck aniversary with a Custom Camper Special and GMC followed in the latter half of that year with would explain it's rarity and lack of information. I should be able to get my avitar picture up tommorow. Any feed back would greatly be appreciated. Thanks

UPDATE: Well, there she is boys... A 1968 GMC Custom Camper Special V-8 2500 3/4 ton 2WD longbed, and I don't know jack about it! I appreciate all the feedback. As you can see finding accurate and credible info on this babe is very difficult to say the least. Any more knowledge out there is welcome.

P.S Also I just measured the bed and it's 8ft. 3in.
