Never needed an extension ONLY because I have dual plug ins......one front and one rear.
BUT if it hadn't been for that there would have been a few occasions where I would have needed an extension cord.
Besides.....25# is NOT going to make/break you on pin weight/rear axle weight.
You need to remove a lot more items. Anything not used in 6 mos. need to evaluate whether it is really needed. IF not...get rid of it.
7 yrs. we full timed and I could open any compartment/cabinet etc. and see/get anything in there w/o having to rearrange the other items.
1 bag in..2 bags out :B
