How Can I Fix The Sagging Floor In My R-Vision Travel Trailer?

This R-Vision travel trailer had heavy people using it and the floor sags or feels mushy between the heat registers.

ANSWER Greetings Rita thanks for submitting your question on our Ask An RV Question Page.

My suggestion is that you take your RV to an RV repair shop and have them look at the floor in your travel trailer. The floor should not be sagging as you describe. In some lightweight trailers such as yours a little play in the floor can be normal, but if it is as bad as you say there may be a problem.

The floor bracing system is part of your trailer's aluminum frame. In fact the floor is attached to the trailer frame prior to the walls of travel trailer being installed. In most cases the walls of the travel trailer sit on top of and are attached to the floor. So if there is a problem with the floor you just can't take the old floor out and put a new one in.

Another cause of a sagging or mushy floor can be that the floor has been exposed to excessive moisture which has compromised and softened the floor itself. The only way you will know is by having your trailer inspected by a qualified RV repair facility.

If it is discovered that the floor needs to be re-enforced or the floor bracing needs to be repaired; it will not be a cheap repair. The bottom of some travel trailers are completely sealed and may involve removing holding tanks, etc.

The only way that you will find out for sure is by getting the inspection done.

How to replace a sagging floor
by: Dan

The only way to do it right is to remove camper from the frame. I just did this to a palomino 21 foot camper. If you under take this project you better be good with tools and have some building know how.

This is what I did. I lowered the nose of the camper as low as I could. Then screwed a 4 x 4 to the sides on the back corner. Make sure you hit the aluminum stud. I used (2) 3/8 x 6 in. lag bolts about 10 in apart. Then I removed the screws from the bottom that went up through the floor into the wall. I found 4 on each side about 6 in long and a lot of smaller screws on the front and back. Not to mention all the screws holding the aluminum trim you have to remove before you can get the the longer screws I already mentioned. I also remover all the interior walls and cabinets that were attached to the floor. Furnace hot water heater refrigerator also need to be removed. Then I raised the nose of the camper carefully removing any wires and cables that went through the floor along with the plumbing pipes. Once it's raised all the way up I put 4x4s on the sides in the front. Then lowered it down and carefully pulled the trailer out.

Before you rip the old floor off measure everything length width and all holes in floor. Take your time and take good not sure this will save time in the long run. Then rip up the old and put down the new. I used 1/2 inch ply then 2x4 on the sides 2x6 front and back with 2x3 16 in on center. I used liquid nail and screws to put it all together then I put an inch and a half blue foam make it a tight fit. More glue and 1/2 inch plywood on top and screwed down. This is thicker than the old floor and about 300 pounds heavier. Put the trailer back under the camper she'll. The 4x4 will help keep it aligned but be careful not to knock them off. Then raise the nose and remove the front 4x4s carefully lower the nose til the back 4x4s are off the ground and the shell is back on the trailer. Remove back 4x4s. Now screw the shell to the new decking. Remember the floor is thicker so use longer screws. I used hardened structure screws that I found at home depot $12 for 10 screws. Make sure you hit the aluminum frame in the walls when you put the screws up through the floor into the walls. I undercoated the bottom to prevent rot and put the interior back in. Took me 3 weeks by myself. Good luck this is a big job.

Saggy floor in Our R-Vision
by: Don

We have a 2009 R-Vision Trail Sport 22 footer. That was the last year they made them before R-Vision went bankrupt and was bought by another company. I looked for all sorts of nasty reasons why the floor in the high-traffic area by the door and table would feel saggy under foot. The only thing I found was that the composite laminate flooring (light weight) has compressed and is fatigued from constant foot traffic.

I am not a small person. 6'2" and, for a while, 260 lbs. I am down to 210 now. You get the picture. No one in my family is petite. I put a 2x6 underneath the problem area and the floor got much better. This spring I'm going to put another in to finish the job. There are no leaks, no plumbing in that area so as far as I can figure it was/is substandard flooring material.

Mushy Floor is Most Expensive Repair you Can Have
by: Michael Scott

I don't own a travel trailer.....but I have close friends who have owned three.
Their current trailer is a 2004 Zeppenlin....I think a 30 footer. The floor around the entrance-way (by the kitchen) has become a sponge over the past couple of months.

When they took it to the most 'qualified' dealer/repair shop they know last week.....they got the bad news: "This could be a ten thousand dollar repair".

The floors on these things are like the spine on a human body; once they go......you're "toast". (They only PAID 8K for the trailer.) DOH!!!!

Resin leveling.
by: Capbob

I am having the same problem with my Gulfstream. I know it was caused by water leaking from the roof which I had repaired. I am thinking of pulling up the flooring to expose the plywood. The sagging is dish shaped between the metal cross bars under the trailer. I will mix some fiberglass resin and pour it into the dish shape inside and level it off. I'm hoping the roughly 2ft area will spread the load and stop the styrofoam core from sagging. I don't know if I need to put plywood over it.Anyone else try this?
