I'm looking real hard at buying a 1986 38' travel trailer, I was wondering if I could haul it with my F-250, 5.0. To give it a bit more beef it has an MSD 6A, K&N, and CARB shorty headers.
Would it be truckocide? I dont know the real weight of the trailer. (over 10k lbs)
Quick response would be appreciated, as It may be tomorrow that I try and get it! Thanks!

More info... I am looking to get the supersprings also. It also has 33" tires to mess up gear ratios and a 4" lift.

I'd say too much trailer for a 5.0L. I don't remember a HD F250 having a 5.0L, they start with a 5.8L, so it may be a light duty F250 which would mean no full floatig rear axle and lighter axles and springs.
