Horse Power

[dickschaak]

I am looking at a Travel Supreme 42. It has a 400 Cummins. I am wondering if that is enough horse power, pulling a 1500 Silverado up mountain roads.

Look at the torque rating which is what you want. That is the 'grunt' factor. Horsepower is great for drag racing where rapid acceleration is required.

Should do just fine. I think that engine has a published max torque of 1150 or 1200 lbs. No sweat.

you will have plenty of power

1200 is correct.

Lotsa tug--no lug--yer fine. Relax and enjoy the climbs.

yep you'll be just fine. I have owned a Insignia Select 42' 400hp for 4 years [moderator edit] can assure you it will do anything you want. Been to CO, MT, ID, NC, many mountain states pulling a Jeep 4 dr. I also own a Select Limited 600hp and recently returned from a trip over the same roads as the 42' could not tell a lot of difference as 40 mph is usually top speed anyway. I noticed a big difference in the engine braking...the 600 even in low stage (of 3) is almost too much, where as the 400 in low stage (of 2) seems to maintain a better "traffic speed" down hills.

Is that the ISL that had a recall?
Check for a Red Light in the dash.

Had a 42' w/400 ISL pulling a GMC 2500 HD w/scooters in the back, no problems for 25k miles based out of TX, been across CO, TN, NC. Those are great coaches.

We pull an H2 Hummer. Don't know it's back there.

[dickschaak]

Thanks, can I ask what the speed dropped to over the mountains?

If it hasn't had a problem yet then it probably won't have. Only a few of the ISL's used in MH's had the wrist pin problem and they went out before 15,000 or very shortly thereafter.

Am curious why there is not much of a speed difference betwen the 400hp and the 600hp cummins. because the road won't allow it or because on grades that steep it doesn't go any faster.

Mountain driving (as refered to previously) and speed is usually detimined not only by the road and safe driving, but also by the traffic and the speed of the "lead" vehicle.
In these situations, 40 mph is most likely going to be your top speed and either the 400 or 600 will do just fine.
However, the 600 will have a higher top speed, for instance 70 mph is usually the posted limit and either will do fine, the 400 will just work a bit harder, but still maintain and outpace many trucks on uphill grades. The 600 just thinks steep grades are flat.
