Towing with f150

Have a question,I am looking at upgrading to a different camper and I am looking at a Rockwood Signature Ultra Lite 8313ss I was wondering if this was to much camper.Previous owner said they pulled with f150 all over (Bristol race) My truck is a 2004 f150 fx4 4 door ext cab gvwr 7150 front gawr 3750 back 3850 wb 133 has 5.5 bed 3.73 axle which I got from owners manual along with 13000 towing cap including truck wt. I do have after market brake control and thinking of adding air assist. The camper has a hitch wt. of 730 dry wt 6204 which I know doesnt really matter because I would be loading camper with supplies,It has gvwr of 7730 camper has wt distrubuiton and sway control hitch .I would be towing it in Ohio (flat land) and we usaully stay within 3 hr drive of home and camp about 4 times a year. I am in the market for F250 but they are hard to find for the right $ and condition.Does anyone have any thoughts?

Well, if I am reading your post correctly on the truck's capacities, total capacity is 13000 INCLUDING the truck weight? So GVWR is 7150, so 13K-7150=5850 towing capacity. At 6204 dry weight (actual weight will likely be 7K+), I'd say it's far too heavy for your truck. However, I may have misunderstood your capacities.

I got the 7150 GVWR from door rail I think thats that maxload for truck including truck wt. Wt.you can haul in bed? The wt of truck I would guess to be around 5500-6000 lbs empty.So I think it would be 13000Towing cap-6000truck wt=7000 I was wondering if anyone else pulls these Rockwood Ultra Lites with 1/2 ton trucks

Right, I understand what gvwr is. You have to consider in gvwr all your passengers, fuel, and then the tongue weight of your trailer (10%). I still think you're pushing it if you want you and your family to be safe.

Comparing it to my F150 with a 145" wheelbase and 9300 lb. tow rating, I feel that pulling my SV 263 weighing in at 5500 lbs. and 28.5' overall, is about the maximum trailer that I would consider. Most of my figures are well in line, except I am nearing my GVWR with a 559 lb. listed tongue weight that has grown to around 700 lbs. ready to camp. With a listed tongue weight of 790 lbs. on the 8313S, that is probably going to grow to around 1000 lbs. ready to camp, adding to the gross weight of the truck. The hitch on that truck is probably not rated for that, either.

The OPer failed to mention the tow rating and what engine is in the truck. The tow rating is either 6800 for the 4.6 L, or 7600 lbs. for th3 5.4 L engine. Even with the 5.4 L, the trailer gross weight is over 1000 lbs. more than the tow capacity of the truck.

More important than all of the weight numbers, is the safety concerns with pulling a 34' trailer with a 133" wheelbase vehicle.....that is 1 long trailer.

IMHO, the OPer needs to look for a much smaller trailer.

A proper setup trailer will have 10% tongue weight. This will make it so the trailer tows as good as it can. This is 10% of the trailer weight, so for a 7000lb trailer, you would want 700lb tongue weight. That tongue weight adds directly to your carring capacity (maybe I should say subtracts from it). It's like throwing 700lbs of bricks in your bed.

Yeah, I'm at 146" WB with my Tundra CrewMax (10,700 towing capacity) and I'm towing a Puma 30KFB (34'9" total length) and I'd definitely say I'm at my max length. It tows great, but I'd hate to go any longer.

I tow a rockwood 8314SS 2008 with a 2003 F150 super cab mainly in michigan flatland it has a5.4 liter 2 wheel drive.Usually only tow about 200 miles handles as well as the 30 foot 1989 trailer I had because of lighweight construction.I have had no problems your trailer looks like it has more tounge weight 134lbs more and total 357lbs more.I would not think that would be a problem with tortion bars on your hitch.Wish you luck hope this helps

Try this...The more accurate your numbers are, the better the overall accuracy. (IE: Don't guess at the numbers. If you don't know them, look them up. Google is your friend!)
