    303RLS measurements

    Hi all just joined the forum because I’m really excited about Grand Designs. We’re looking buying a 2018 303RLS for our permanent seasonal campsite but have some restrictions because of a tree. The unit we’re interested in is a good drive away, so I was wondering if someone could give me detailed measurements of the 2 slide side, because the tree has to fit between the slides, which I think it will by looking at the floor plan. More importantly, I need to find where the side compartment for the water falls. If someone could bother, full measurements from the bumper to front of back slide, front of back slide to rear and front of compartment and front of back slide to rear of front slide. That would give me everything I need to see if it will fit. Thanks in advance and excited about hopefully being an owner of Grand Design!

    Hey @Catman, welcome to the forum. I don't have that model so I can't help with measurements. But there are many knowledgeable folks on this forum, and quite likely one will be able to help you.

    Welcome !
    I don't have exact measurements but here are a couple pics of the slide and placement of the water heater and furnace exhaust. On the large slide there is the rear fridge access.
    Water hookups and tank pull handles are behind the smaller door of the basement.

    How close to this tree are you going to park, limiting access to the water heater back side could be a problem if the heater misbehaves.

    It’s 15’ 6” from a tree in the back with some clearance to the tree between the slides and 8” to the tree from the unit.

    Another thought Is the '19 may have an access door to the furnace in place of the vent alone. Can't recall what year they wised up and did that.

    Unfortunately, I found with your measurements, the back slide would be 6” inches into a tree on the side!

    Hi Catman,

    I have a 2019 303RLS that I will be getting out of storage this afternoon or tomorrow morning. I’ll check to see if Ken’s 2021 measurements are any different than my 2019,
