Note: TT=Travel trailer, TV=Tow Vehicle, WB=Wheel Base, GCVW=Gross Combined Vehicle Weight
In my particular case, I am towing a 2001 Prowler 27H (actually 28' long) with a 2003 Suburban 3/4 ton, and I have an Eaz-lift weight distributing hitch and friction sway control bar. I've towed on a few windy days and really don't notice the trailer moving around much, except when the big trucks pass me by. Then I get a little wiggle out of the trailer, but nothing serious or scary. I'm over the first guideline by 3', which I think isn't that bad, but I would not want to be any further over it. And I'm just under the second guideline. I didn't know about these guidelines when I first bought the combination, but I knew I didn't want to go real long with the trailer towing it with the Suburban.
I put a lot or reserach into safety before purchasing the TT that I did. My prior TV was a 1997 GMC Safari Van (Chevy Astro clone) and I was at my limits for weight and WB when towing a 20' trailer. With that TV & TT combo, I had a very scary sway situation that shook the trailer so bad, all 4 hub caps came off. After much research I determined that besides a rather soft suspension, short WB and >90% of max GCVW, I had too light of tounge weight. I weighed my trailer +van and quickly purchased a trailer tougne scale to ensure that I had 10-15% tounge weight. Even though I was using a Reese Dual Cam system, I had
errantly loaded the TT too light in the tounge causing the unsafe sway condition.
After I purchased my Expededition EL I could now consider upsizing my TT. From my past experience, I knew I didn't want to get too large of a TT for my TV. After narrowing down my decision to an a Trailcruiser model 30QBSS, I posted questions about towing to the Trailercruiser / R-Vision owner forum @
http://www.r-visioncamping.org/ and found many people safely towing the same trailer with Suburbans, regular length Expeditions F150's, etc..
If this was built like a normal aluminum skinned TT, then yes 30' would be too much for weight, height and length, however this is a lower profile aerodynamic smoothwall lightweight TT with a total length of 31'-7" and an overall heigth of only 10'4" with A/C. The empty weight is only #4,500 and about #5,500 fully loaded for travel. With the Expy EL + my family of 7 + TT, I'm about #13,000 which is still #2,000 under max GCVW. I am still using the Reese Dual Cam sway control, but replaced the spring bars with heavier bars for the increased tounge weight. I have towed about 2,000 miles with this rig sofar and absolutely no trailer sway even at highway speeds of 65 MPH and getting passed by Semi's. I also towed about 1,000 miles with a Husky weight distribution system and a cheap friction sway and still had no problems. My new TT is over 10' longer then my last TT and weighs about #2,000 more but with the Expy EL my towing experience is no longer a white knucke experience. I have plenty of power and vehicle control with absolutely no sway in any condition.
My point is, my 30' TT is not unsafe with my Epxy EL. Safe towing has much to do with the TT design, hitch setup, sway control, TT loading, TV size, and of course TV WB. I'm an Engineer and am very confident decision I made for my Tow Vehicle and trailer without any compromise in the safey of my family or others. BTW, I would not tow this TT with the non EL Expy.
