Question Will I have trouble towing newer fifth wheel?

So, this year end of july, start of august, will be off to Osoyoos B.C., then will be taking Anarchist Summit out of osoyoos up and over the mountain to Rock Creek B.C.
So as we bought a newer and larger fifth wheel which is a 2004 Wilderness lite model 245 RK with one slide out and an overall height of around 12 feet I am wondering now if I will be having any issues as we kept the old truck, a 1996 GMC K2500 with a 454/7.4litre engine long box 4x4 with the 4L80E tranny which has the engine oil cooler, and a tranny cooler, and it has A/C on it I believe the rear end was a 3.73 ratio I have had to replace the radiator last year, and previous to that the dealer had to redo the intake manifolds due to an anti freeze leak and now I am wondering if this truck will handle the load.
And what is the best way to approach a long climb up and a long run back down the other side, no tow haul switch, so what is the best way to set up for going up and down, it does have a tach so I can try and fiind a range to stay in, but should one expect to pull right down into first up and down the hill, I know not to pull in the o/D shift position, any tips?
Went from a 22 foot coachman Catalina to this one, this newer one measures pretty well 24' 6" in length but it is so darn tall and we have only brought it from the dealer in November to the house where it has sat since, it does have marathon tires on it, so hope they will be okay also.

Live life with no regrets.

Bigger is always better, but I think you will be OK, My father in-law pulled a trailer that size with his 1978 454, it would be nice to have a 4:10 in the rear, My nephew pulls a 24 ft Jayco with a super slide and a 18 ft ski boat behind the trailer with a 8.1 Chevy gas. I would do it.

Don't get in a rush to climb a steep grade. You will quickly find the optimum towing RPM and the automatic transmission will not allow you to lug the engine, BUT, if you notice your temperature gauge climbing you can manually select a lower gear to reduce engine temperature and reduce speed accordingly.

Trip to Rock Creek

I don't think you will have a bit of trouble. Your 454 is quite a wheel horse. A 4.10 diff would be the best but a 3.73 is only one notch faster. I would avoid any tendency to let it lug on the long grades - this will help the cooling situation. I drive gross weights up to 45,000 kg. on the farm (class 1 commercial) on the farm. A good rule to remember going down grade is start down at slow speed and descend in the same gear or lower than you would climb a similar grade. Check both your tow vehicle and trailer brakes over well before the trip. A transmission temp gauge might be a good addition. The pull up the Coquhalla to Merit will be every bit as tough as the Anarchist. Good luck - enjoy the new rig - I will watch for your results.

So found out one more thing, tire code says these tires were made in 6th week of 2003, so I think after all I have heard that maybe these 8 year old Goodyear Marathons load C ST225/75R15 should be given the old heave ho and new Maxxis that I have used on previous units be purchased instead in a "D" rating at least.
Although they look great, and the tire place I called said they sounded still good, but me thinks I will pull at least on off and take in and let them see them, I bought my last tires from this place in 2005 so they seem to know tires.

Live life with no regrets.
