Help, first time TT buyer.

you might only be able to pull a smaller "pop up" and not a hard body TT like you want. suggest you invest in a stronger truck.

That vehicle will very likely not be suitable for what you want to do with it and will scare the bejeebers out of you towing or result in an early death of the vehicle.

NewBee,
I'd suggest two things.
First, find an online towing capacity calculator spreadsheet. You'll need numbers from the sticker on the door jamb of your tow vehicle and from your owners' manual. The various limits will be specific to your vehicle, including its engine, transmission & tow package. When we did this before buying a trailer, we had to make some guesses & assumptions about what the trailer would weigh. Some number will be your limiting factor - likely tongue weight or gross combined vehicle weight (truck + trailer total). Use 15% of the trailer weight as the tongue weight in your estimates. All this will give you a maximum weight your trailer can weigh, including all options and everything you put in in (plan on 500-1000 lbs worth of 'stuff').

Second - right now is RV show season. Go to the nearest show. Take a camera and notepad and look at floor plans and layouts. Look for the basics, don't worry about options & shiny flashy details. Do you like hybrids (beds slide out)? Bunk beds? Bathroom in the middle of the trailer or at the end? Do you need a bed you can walk around or is climbing in ok? Look at the ones in the range of what you can tow. Look on the trailer tongue or near the door for the sticker that tells you the gross vehicle weight of the trailer. This will give you some ideas as you look at used trailers.

Good luck in your search.

We agree with prior posts - we tow a Lance 1685 (20'9") with a 2006 4 Runner 6 cyl. Towing capacity is 5000#, trailer is 3800# dry, but way too close to our max loaded.

After 10,000 miles, here's a post I wrote on Pros and Cons: http://trailertraveler.net/towing-travel-trailer-with-a-6-cylinder-4-runner/

My husband said I could buy a trailer, but couldn't have a new truck... so the compromise. One of these days we'll get a new tow vehicle and we'll have more margin for safety. In the meantime, a 24' trailer is going to weigh alot more than our 20 footer, we wouldn't do it. Just our .02 cents worth...

I think you'll be a lot happier if use the value of the 4-runner to get a more capable TV and an older well maintained TT. Pulling any high walled trailer is a lot more work than you've pulled before and requires a lot of power to maintain 60-65mph.

There were no payload/Tire and Loading stickers in 2002.

Yup, see if you can find the max payload,sometimes on a door sticker.

That is the weight you can haul; it includes people, pets, gear and tongue weight.

I pulled a rented TT with an F-150 that had 200,000 miles. Once we decide on the TT we wanted we traded for a suitable TV.

That is essentially a Tacoma, and I think it has the 3.4 6 cyl? Towing capacity if I remember my Tacoma right was 5000 lbs. The rub is that the payload was like 800 and that is the limiting factor. I think you will want to stay under 3000 pounds for the dry weight of your trailer and that may mean a 21 or 19 footer. I towed a hybrid which gave plenty of room because you're not giving up floor space for the beds.
