K.N.
We tow a 2-horse trailer, not a camper, so I'm not sure if the comparison is valid. My husband has 2001 Chevy Tahoe with over 225K miles -- and it's still going strong. Seats 8 and tows like a dream though New England mountains and hills (OK, so they're not the Rockies -- we still have mountains!), along back roads and on the highway. The 2 horses alone weigh about 3000 pounds, not counting the weight of the trailer itself.
Hope this helps.
