Tub/side seals, easy job?

Hallo, some advice please, I have a 97 solid side 110 and have a couple of small leaks coming through the seal between the tub and the sides.
Is it an easy job to unbolt and lift the sides to replace the seals or is there a simple easier fix for what are just small leaks?
I am hoping to convert to a camper so will eventually be boarding up the insides.
(Just to say I am a newbie to LRs, and female, so don't get too technical!) Thank you.

When i changed the side panels on my 90 I undid all the roof bolts except the ones on the windscreen panel, and lifted the roof up and held it up with a bit of wood while I removed the panels. I had windscreen panel hinges so it pivoted. Not sure if you have those on that year but it might lift up enough. Think there is 3 bolts holding the panels down to the tub. Don't forget to remove the top hinge on back door. Not too bad of a job just a bit time consuming with all the bolts

It is not to difficult to unbolt the roof sides from the tub and if you then release the wind screen to bulkhead brackets the roof/sides can be lifted and propped with timber at the rear for access to the seal. Help will be needed to do this and ensure all is set up safe for the job.
If you can see where the water is getting in then some flexi sealant can be tried along where the seal contacts the tub capping. The seal can crack or get stiff with age.

Thank you both for your replies, I might try the seam sealant first as the leak is only minor, hopefully that will solve it.

Try to find some PU sealant, or similar paintable stuff. Not silicone, which isn't. But if you're never going to paint it then it doesn't matter.

Thanks everyone, I've applied a bead of silicone sealant, and it hasn't rained since!
