5.5 or 7kW Generator in Canyon Star?

We are continuing to look at new Canyon Stars and one option offered is a 7kW Onan generator. The standard generator is 5.5kW.

We will likely go with 10 cf Frigidaire refer (dedicated PSW inverter), and 13.5M heat pump AC units. Looking at other AC loads such as washer/dryer, the battery charger and misc items.

My question is, do I NEED to upgrade to the 7kW generator for those infrequent times when I'm boondocking (no washer/dryer and no electric hot water) in the summer time when I WANT to run both AC units? If I stay with the smaller generator, how likely is it that I will ever be challenging the generator? I figure 45 amps available from the generator should be plenty and more efficient at lighter loading.

I do intend to install 200-400 watts of solar in the future, but I don't think that really plays into this decision.

Your thoughts?

Wes

Looks to me like you better watch the NCC with all your upgrades especially with the bigger generator.

We have the 5.5 which is plenty of power but had they offered the 7.0 when we bought ours I would have done that. When you say no electric on the water heater, I'm assuming you just wouldn't use it while boondocking. I would definitely get the water heater with the electric/gas option. We use it all the time and even when boondocking, we just don't run it with the AC's on although it would probably be ok.

As to the comment on your NCC, first of all the generator is not going to be enough of a weight difference for it to be a deciding factor. Ours is built on the 26K chassis, which leaves us over 5200 pounds of NCC, so you shouldn't have any issues with whatever options you add if they are using the 26k chassis. Even with the 24k chassis you would still have about 3200 pounds NCC. The 26k chassis is definitely an option I would get if not already built on it.

We haven't had a problem with the 5.5 either. When we run it we can run most everything including the HWH on electric. The EMS takes care of load shedding when necessary, it dumps thw HWH first.

As far as weight is concerned, the 7KW weighs about 11lb more, 290 vs 279. Should not be a problem.

I Agree with getting the 26K chassis, I would have if it was available in 2008. Our rear axle is only about 200lb below GAWR with us fully loaded.

Thanks for all the feedback. I'm not seeing the justification for paying for upgraded generator.

Do the new Canyon Star have Electric Management System? I thought that was only on diesel pushers.

In 2008 they did, just looked at the 2016 brochure and it's still standard. Ours is in the panel above the door and is an Intellitec but I believe they changed manufacturers recently.

Ours came with the Electrical Management System, I think that was standard equipment. Ours is also in the panel above the door, along with all the gauges for holding tanks, water heater controls, satellite switch, big slide switch, step switch ect. How much did they want for the generator upgrade?

Said no one ever: "Gee, I wish I had gotten a smaller generator"!

Well, when we ordered our '02 Dutch Star it had a NCC of 5,200#'s and we didn't order the real tile floor nor washer/dryer. When it was delivered we only had 663#'s of CCC! We did get the 8.0KW diesel gen and storage bay refer/freezer and hardwood cabinetry.

5.5kw and 7kw uses the same engine so weight should be close to the same. Read specs. I would definitely go with 7kw.

Maybe they do a better job of figuring that out now, as ours is right on the money. We will never come close to maxing out our weight capacity. I know in our last RV I always worried about being over our capacity, with our Canyon Star it will never be an issue.

The 5.5 in our Canyon Star handles the load quite well. We do not have a residential fridge but do have the larger AC/heat pump option and stack washer and dryer, electric/gas hot water heater plus all to other "usual" stuff. I can only think of one time in the past three years of rving when we tripped the breaker while turning on too many electrical devices and running on the generator. You'll probably be o.k. with the 5.5. If budget allows the 7 would probably give worry free power. As with other posters I doubt that weight will be much of an issue, if it is an issue at all. We too have the 26,000 lb. chassis.
Whatever you decide we hope you enjoy your future coach. They're a great unit in our opinion.

Thanks for all the replies. We put a deposit on a 2016 3710 today, just need to work out a couple of questions on our end before completing the deal.

This will be our 3rd RV, upgrading from a 32' Sunseeker.


Cheers!
