Narrowed choices down.............. I think :)

What numbers are you comparing? As-built or max for the TT?

The reason I ask is my manufacturer rates the max for the TT based on axle and tire ratings. So they have at least 5 very different TT's that all have the same max number.

You could be running into that type of difference between 2 different makes.

I bought my Premier new back in 2011. I would buy it again if I had to do it over. It is holding up well. I enjoy leaving the frameless windows open during the rain. It tows really nicely. On the flipside, I hear Jayco has a great reputation.

My 28' Keystone Bullet (with many more options and a slide) weighs only a few hundred pounds more than my 24' KZ Jag did, mostly because of the materials used in the frame.

I always wondered whether there were any criteria for use of the terms "Light" and "Ultra Light" when it comes to naming TTs. Somehow I doubt there is any standardization or requirement for that.

========================

Have had a Jayco Eagle and a Keystone Cougar HC trailers. Keystone beats Jayco in quality workmanship by far. Wife always complained about all the staples that Jayco used. Said she never wanted another one.
Next week we will order a Rockwood 8310SS trailer with six sided aluminum frames. An BTW Forest River has a 2 year warranty for a $150 adder.
Construction between Jayco & Rockwood are light years apart.
Happy trails,

We are on our third Jayco in 4 years. We started with a 22FB then 6 months later traded up for a Jayco 24FBS with a slide and then last July we traded that in for a Jayco 266RKS. Its WONDERFUL. We love it. My husband is a real fusbutt for the way things are made and the strength and durability of equipment. He is a mechanical engineer with 51 years experience in design, service and repair to mention just a few things. We went to the Jayco factory and watched their 5th wheels being built and the 266RKS trailer is built the same way. We were very impressed by the way it is built etc. I know one thing for sure - you get what you pay for!
We have just been away camping here in Florida a week ago and had a wonderful time. We visited the Tampa RV show which is the biggest one in this area I believe. We did not see a trailer of comparable length with everything that we have in ours. Sure if you go bigger you will find more stuff but ours is a perfect size for two people.

Good luck with whichever trailer you get and I'm sure you will love cammping in it.

Wonderful info. The Eagle looks nice as does the Premier, but I can get much more trailer with the Premier.

Jayco is made with heavier materials as well as heavier slide design.
Jayco uses wood trusses in the roof and floor.
Jayco uses the heavier rack and pinion type slide out mechanism.
Not sure but Jayco may use 2" aluminum for wall studs. They're aluminum for sure though.

Keystone Premier uses aluminum roof and floor trusses.
Schwintek type slides instead of the heavier rack type.
1-1/2" thick aluminum wall studs.

Keystone will use lighter weight materials inside as well.

Jayco has consistently higher CCC's than Keystone, which means Jayco is using stronger frames as well as heavy duty tires and suspension.

Go look at how the drawer construction is done on both. Jayco uses thicker wood for drawer fronts.

2 year warranty for Jayco vs 1 year for Keystone.

Jayco wins hands down.

We love our Premier too. Well built, no problems and light for its size. Aluminum is a big part of it.

As others have noted, the weights add up. A little here, a little there. Some of the areas where the differences can be:

1. One manufacturer is more accurate on the weights leaving the factory. IE: Some trailers have a few options installed, after the weight sticker has been put on it. Some have more options installed by the dealers, thus shipping weight on the trailer is lower. It's possible, they'll weigh pretty much the same, when leaving the dealer lot.

2. Different building materials. Wood / aluminum in various places.

3. Different options installed.

4. Different sized wheels and tires.

5. Different materials used in cabinetry.

6. Different sized propane tanks.

7. Different sized holding tanks.

8. Different "R" value insulation.

9. Underbelly enclosed / or not.

10. Different frame structure. IE: "I" beam vs "C" Channel vs Tubular, along with thickness of the steel.

All added up, one could easily weigh 1500 lbs more than the other.

Not sure what the Jayco is made from but the Premier is an aluminum frame. If Jayco is wood, that will be a big part. Then there are little things like 20 lbs propane tanks and the like that lower the weight. We love our Premier.
