Been quite awhile since visiting here on the forum. I am considering trading the 97 American tradition in for a 2014 35B' Itasca Sunland. Still has the heavier wheel base as opposed to the smaller coach. The smaller coaches seem too light to me. My question is whether or not the Itasca will pull the grade up the California grapevine. It has the Ford v10. I have never had much success getting over that grapevine any faster than 35mph in my diesel towing my small 12' trailer. That coupled with the coach carrying too many memories in the loss of my husband dieseldave. Time has came to move on. I value your input and have not taken delivery of the 2014 Itasca yet. It is a beautiful coach but want to make sure it has the power needed to pull those 6% grades?Input appreciated.

You will certainly be able to get to the top of the grade without any question; the only real question is how fast you'll be going.I would guess (but I don't know for sure) that, with the pedal to the floorboards, you'd be going faster than 35 mph, perhaps closer to 45 or maybe even 50. The engine will be sounding like it's about to thrash itself to death, though it won't and in fact it would be fine running all day at those high rpms.

Those are pretty bulletproof engines and so are the transmissions.Are you still pulling that trailer ? 2 things to learn. What is the rear axle ratio and does it have the biggest radiator available ? (Smaller Ford trucks had 2 different size radiators; standard and heavy duty if equipped with the trailer tow option.)Bigger radiator is always better. If you are struggling on hills, you may need to change the rear axle ratio to a higher number.

Ok thank you two! I will check out the radiator on the new coach.

Pulled the Grapevine many times with my 2000 V-10 at 25,000 Combined Gross Wt. Newer V-10's are more powerful. If your trailer puts you near the CGW rating you should have a transmission temperature gauge. If the tranny temp gets too high you will need to use a lower gear and give up a bit of climbing speed. The V-10 absolutely will climb any hill - gear, speed, and engine noise will vary - well the engine rpm necessary to get horsepower will always produce lots of noise.

If you can afford the extra $$$ for a newer Class A, the 2016 model year introduced the 6 speed transmission and pulling hills with that extra gear became easier.

Check if you can test drive it to Bakersfield spend the night and return....

Went over the Grapevine twice this week. Guy in a 36 foot Class A gas passed me. Had to be a Ford as it was fairly new. I think you'll do fine.

The V10 makes more peak horse power than the diesel in your American Tradition. It really should pull that 22000 lb Itasca up a 6% grade at 45 mph. It needs to be screaming pretty good to do it though....the peak hp is at 4750 rpm.

Sorry to hear about the loss of your husband and figuring this stuff out can be daunting. I would suspect that your older DP is probably close to twice what the gas MH weighs. Also compare the HP of your older DP to the 362HP V-10. HP/wt is what will determine your performance. A simple test is to see how long it takes your DP to go from 40-60 MPH on a flat and then test the Gas MH the same way. If the gas MH is quicker and I would suspect it would be you will also be quicker on the hills. Good Luck on finding the right MH for you.
