We are very happy with our 2013 28RBS cougar xLite, and just completed a cross country trip with no issues with either our tow vehicle or trailer
Before the trip I upgraded the stock tires to Michelin M/S2 Load E rated tires and upgraded the front rotors and pads to heavy duty service parts.
Although our 2010 F150 (5.4L 4x4 Screw)came with the tow package I still needed to swap out the stock mirrors to the extendable tow mirrors.
Our truck is set up with a 1,200/12,000Lbs Equalizer hitch system.
The truck tow capacity is 9,600Lbs with a max CGVW rating of 15,500Lbs
The trailer has a dry wieght of 6,300lbs (8,200lbs gvw) and I estimated that we had about 1,000lbs of cargo in the trailer...so towing about 7,300lbs.
I kept the bed of the truck basically empty and stored all my tools and cargo in the trailer's rear cargo bay.
We started our 5 week road trip from Kettleby Ontario (~30km N of Torono) and our main destination points (stayed a min. of 3-4 nights)were:
1) Killbear Provincial Park, Parry Sound ON
2) Lake Superior Prov. Park, S of Wawa ON
3) Tunnel Mountain RV Park, Banff AB
4) Whistlers Campground, Jasper AB
5) Whistler RV Campground, Whistler BC
6) Bella Pacifica Campground, Tofino(Vancouver Island) BC
7) Grizzly RV Campground, West Yellowstone MT, USA
8) Chutes Prov. Park, Massey ON on our finnal leg home.
We stayed at many other campgrounds for just 1 night as we were traveling to our main destination point.
Overall the truck performed beyond my expectations as a 1/2 ton and I was able to easily maintain the 110km/hr speed limit (cruising with the traffic at 120-125 km/hr) on the Trans Canada HWY 1 thru the prairie provinces and the Alberta flats.
On the US I90 thru WA, Idao, Montana, and I94 thru North Dakota the truck had no problems maintaining the 75mi/hr speed limit (@2500-3000rpms) on the flats and obviously worked hard on the 6-8% or more on uphill grades and easily went at the pace of any transport truck ahead of us...going downhill was always half the fun.
With over 10,800km (6,480mi) we never experienced any significant sway passing or being passed by huge transport trucks...slowed down when we ran into cross winds going thru Vantage WA.
In my opinion our most difficult drive was the section from Lillooet BC to Whistler BC thru a narrow winding, down hill, single-lane swing bridges section of Hwy 99...The tranny and breaks got a real workout and I was happy that I serviced and upgraded the front brakes before our trip...after that run every other mountain pass was a breeze...even the drive from Naniamo BC to Tofino on the Pacific Ocean side of the Island.
Would we do the trip again? Yep in a heartbeat, great experience for the whole family and got to see much of our two great countries
And to answer the original question ....the 28rbs is a great travel trailer to tow as long as you have your hitch WD system setup optimally and your truck is up to the task.
Sorry to be long winded, and hopefully some of this info is helpfull to someone planing a similar trip.
Happy camping all......Chuck.
