Question Ultra Lite Trailers

I have a Ĺ ton Toyota Tundra, so Iím looking at Rockwood Ultra Lite trailers. (I like the 2604S). I notice that other manufacturers, like Keystone, weigh 1K or more lbs for the similar floor plans. I realize that some of the weight savings is because of the aluminum frame. But what are the other weight-saving factors that make this difference? Are there any concerns with Ultra Lite trailers, like less sturdy construction?

I'm towing a 2502 with my Xterra, which is limited to 5000 lbs. Tows it fine, I just leave the transmission out of O/D. Puts me in 4th gear ~2500-2750 RPMs.

I would have concerns about an Ultralite too. However, my buddy has owned is Rockwood TT since 04, and has traveled from FL up to Canada -n- back the first year, then from FL to Oregon -n- back the next. They've been fulltiming many months each year. Their camper still looks new. I was so impressed, I ordered a smaller version. Don't let the Ultralite label fool you, it's well made.

Here's a picture of my frame:

Here's a picture from inside the storage bay. Note the aluminum framework that supports the bed above:

Aluminum framework is also used in the dinette frame, and in the walls. Very strong yet lightweight.

There's no noticible flexing of the floor.

Can't tell you what all they did to save weight, but they did use Filon walls for the exterior, and the roof is a few inches of foam with about a 1/4" luan skin on it. Strong enough to walk on, yet saving a lot of weight.

I would buy one again without hesitation. Good luck on your quest!

We started out towing ours (see sig) with an E150 conversion van. Dry weight is listed at 4300# - never did weigh it fully loaded. The van did fine but was getting old & tired and got replaced with a pickup so we can take the kayaks, bikes, & stuff without putting any toys in the trailer.

The low profile & aerodynamics and fully enclosed underbelly of the trailer add to it's great towability. The only down side is the ground clearance at the rear. I learned I need to take driveways (gas stations, parking lots...) at an angle to avoid grounding the back of the trailer.

I will look at another if/when the time comes.

You have asked a great question. To be honest, I don't know what makes my trailer weigh 4800 lbs dry weight vs. the same floorplan from Jayco that weighs 5600 lbs dry vs. a Slaem that is 6400 lbs dry. I think the slides are deeper on the heavier models. Don't know about anything else.

I tow a Rockwood 2701SS with my 2005 Tundra 4x2 double cab. It is max'd out but does very well. Would have loved to get an 8317SS, but it was too heavy.

Question Question about your O/D use in this post.

Hey guys, I noticed that you guys are mentioning driving without using O/D. I have just picked up our first TT. I have the Flagstaff 831KRSS dry weight is 6205 or so. I am pulling with a 1500 Dodge Ram Quad Cab 4x4, with the Hemi. I am supposed to be able to pull 8900lb minus the 4x4 weight which I was told takes off 500lb. This leaves me tow rating at 8400.

So, I was told that I am to have O/D on ALL the time when I am pulling the trailer? Could you guys expand on how you use O/D when towing?

Thanks, Frank

I have always let the truck tell me when to use OD or not. If it is downshifting a lot, I just leave it out of OD. Unless I'm going downhill, my Tundra tranny won't even shift into overdrive with my 32 ft trailer.

Does your owner's manual say anything?

Frank, look at your manuel for the truck it will relate information to towing with od off or on,
my expedition states can turn od off when towing on hilly terrain, if I notice a lot of downshifting from od to d while towing i turn it off, saves the hassle, but on flat or gentle rolling i leave it on to get the lower rpms of od,

also on down hill with od off you will have a little more engine braking and less need for tapping brakes to keep speed down,.

Best advise is go by vehicle manuel.

To the original question, why is it lighter?

Smaller holding tanks, curtains instead of doors, fewer cabinets or less fancy cabinets, plastic potty instead of ceramic, fewer interior walls.

You can build a quality trailer that's well made doing these things. It all adds up.

Hello and we just purchased a Ultralite 2603 and pull it with a Hummer H3...bit of a load on hills but other than that..does just fine. These seem to be a very well built product...other than the factory drilled a dozen holes in the wrong place...hanging something crooked or what ever...just walked away and left the holes. Poor workmanship in my opinion. Outside work was fine...some dooped up stoner doing inside trim out on a Monday morning....had a real bad hangover...
